Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a method for preparing a carbon nanotube composite structure. [Prior Art] [0002] A carbon nanotube is a hollow tube rolled from a graphene sheet. Nano carbon tubes have excellent mechanical, thermal and electrical properties and are used in a wide range of applications. For example, carbon nanotubes can be used to make field effect transistors, atomic force microscope tips, field emission electrons, nano templates, and the like. The application of the carbon nanotubes in the above technology is mainly the application of the carbon nanotubes on the microscopic scale. ο, the operation is difficult. Therefore, it is of great significance to make the carbon nanotubes have a macroscopic structure and to be applied at a macroscopic level. [0003] Jiang Kaili et al. successfully extracted a nano carbon pipeline from a carbon nanotube array in 2002, with See the literature "Spinning Continuous Carbon Nanotube Yarns", Nature, V419, P801. The nanocarbon pipeline is composed of a plurality of carbon nanotubes connected end to end and arranged in a preferred orientation in the same direction. [0004] However, the bonding strength between the carbon nanotubes in the nanocarbon pipeline is weak, so the mechanical strength of the nanocarbon pipeline needs to be further improved. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a method for preparing a carbon nanotube composite structure for preparing good mechanical properties. [0006] A method for preparing a carbon nanotube composite structure, comprising the steps of: dissolving a polymer in an organic solvent to form a polymer solution, the contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees; And a carbon nanotube structure of a support structure from 099122581 Form No. A0101, No. 3/37 pages 0992039783-0 201202319 is impregnated in the polymer solution to composite the polymer with the carbon nanotube structure. [0007] A method for preparing a carbon nanotube composite structure, comprising the steps of: dissolving a polymer monomer in an organic solvent to form a polymer monomer solution, and contacting the organic solvent with a carbon nanotube; An angle of less than 90 degrees; a carbon nanotube structure of a self-supporting structure is impregnated in the polymer monomer solution: and polymer monomers in the polymer monomer solution are polymerized to each other to form a polymer, and Composite with the carbon nanotube structure. [0008] Compared to the prior art, the carbon nanotube composite structure dissolves the polymer by selecting an organic solvent having a contact angle of less than 90 degrees to the carbon nanotube, thereby enabling the polymer to be sufficiently wetted therein. In the carbon nanotube structure, it is tightly bonded to the carbon nanotube. Thereby, the carbon nanotube composite structure prepared by the method has excellent mechanical properties. [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. [0010] A method for preparing a carbon nanotube composite structure according to a first embodiment of the present invention includes the following steps: [1011] S10, dissolving a polymer in an organic solvent to form a polymer solution, the organic solvent The contact angle of the carbon nanotubes is less than 90 degrees; and [0012] S20, a self-supporting structure of the carbon nanotube structure is impregnated into the polymer solution to composite the polymer with the carbon nanotube structure. [0013] In the step S10, the type and nature of the polymer are not limited and may be selected according to actual needs, and only need to be dissolved in the organic solvent. The polymer may include polyacrylonitrile (PAN) 099122581 Form No. A0101 Page 4 / 37 pages 0992039783-0 201202319, Polyvinyl alcohol (PVA), Polypropylene (PP), Poly Any one or any combination of polystyrene (Ο PS), polyethylene vinyl chloride (PVC), and polyethylene terephthalate (PET). The degree of polymerization of the polymer can also be selected according to the actual operation. Generally, when the polymer is polyvinyl alcohol, the degree of polymerization of the polyvinyl alcohol is between 1,500 and 3,500. The mass percentage of the polymer in the polymer solution varies depending on the polymer and the organic solvent. Generally, when the polymer is polyvinyl alcohol, the mass percentage of the polyvinyl alcohol in the polyvinyl alcohol solution is substantially between 1 ° / 〇 to 9%, so that the polyvinyl alcohol solution is infiltrated in the When the carbon nanotube structure is described, the specific surface area of the carbon nanotube structure can be reduced as much as possible.

Preferably, the organic solvent has a relatively large surface tension while being capable of dissolving the polymer. Specifically, the organic solvent may have a surface tension of more than 20 mN per meter and a contact angle to the carbon nanotubes of less than 90 degrees. The organic solvent includes dimethyl hydrazine (1^11161; 11713111 卩 11 〇乂丨 (16, DMS0), Dimethyl Formamide (DMF), 2, 5-dimethyl ketone Any one or combination of (2, 5-dimethyl furan) and N-methyl 2-pyrrol idone (NMP). Since the solubility of the organic solvent is based on the polymer number 099122581 A0101 page 5 / page 37 0992039783-0 201202319 different, therefore, the choice of the organic solvent also needs to be selected according to the specific polymer. For example, when the polymer is polyvinyl alcohol, the organic The solvent may be selected from the group consisting of dimercaptopurine. The surface tension of the dimethyl hydrazine is approximately 43.54 milli-Nilometers per meter and the contact angle to the carbon nanotubes is approximately 70 degrees. The contact angle of the tube is complementary to the angle of the organic solvent to the saturation angle of the carbon nanotube. The smaller the contact angle of the organic solvent to the carbon nanotube, the structure of the polymer to the carbon nanotube structure The better the wettability, the closer the polymer binds to the carbon nanotube structure. The greater the surface tension of the agent, the better the wettability of the polymer to the carbon nanotube structure, the stronger the ability to shrink the structure of the carbon nanotube, the polymer and the carbon nanotube The closer the structural bonding is. [0015] The carbon nanotube structure is a film-like structure, a linear structure or other three-dimensional structure composed of a plurality of carbon nanotubes. The carbon nanotube structure is a carbon nanotube The self-supporting structure, the so-called "self-supporting" means that the carbon nanotube structure does not need to be supported by a surface of the substrate, i.e., the edge or the opposite end, and its unsupported portion can maintain its own specific shape. A large number of carbon nanotubes in the supported carbon nanotube structure are attracted to each other by Van der Waals attractive force, so that the carbon nanotube structure has a specific shape to form a self-supporting structure. When the distance between the plurality of carbon nanotubes in the carbon nanotube body is between 0.2 nm and 9 nm, the carbon nanotubes have a large van der Waals force, thereby The carbon nanotube structure is only passed through The self-supporting structure can be formed by the tile force. [0016] The carbon nanotube structure can include at least one carbon nanotube film, when the nai 099122581 form number A0101 page 6 / total page 3792039783-0 201202319 [0017] 99 〇 [0018] 099122581 When the rice crucible tube structure includes a plurality of carbon nanotube membranes, the 'multiple carbon nanotube membranes are disposed' by adjacent vana carbon nanotube membranes combined by van der Waals force Please refer to m, the carbon nanotube structure film can be a carbon nanotube flocculation membrane, the carbon nanotube flocculation membrane is a carbon nanotube raw material, such as a row array, flocculation treatment Obtained - a self-supporting nano carbon tube structural film. The carbon nanotube flocculation membrane comprises intertwined and uniformly distributed carbon nanotube Y carbon nanotubes having a length greater than λ, preferably from a micron to a micron diameter so that the carbon nanotubes are intertwined with each other. The carbon nanotubes are mutually attracted and distributed by van der Waals forces to form a network structure.

The carbon nanotubes are laminated The carbon nanotubes form an angle /3 with the surface of the growth substrate forming the carbon nanotube array, wherein yS is greater than or equal to 0 degrees and less than or equal to 15 degrees, and the angle is cold and the pressure applied to the carbon nanotube array Relatedly, the larger the pressure, the smaller the angle, preferably, the carbon nanotubes in the carbon nanotube rolled film are arranged parallel to the growth substrate. The carbon nanotube rolled film is a nanometer by crushing. The carbon tube array is obtained, and the carbon nanotubes in the carbon nanotube rolled film have different arrangement forms depending on the manner of rolling. Specifically, the carbon nanotubes can be arranged in disorder; see FIG. 2, when When rolling in different directions, the carbon nanotubes are arranged in different orientations; when rolled in the same direction, the carbon nanotubes are arranged in a preferred orientation in a fixed direction. The carbon nanotubes in the carbon nanotubes are laminated. The length of the tube is greater than 50 microns. [0019] The carbon nanotube rolled film 5纳米至100微米之间。 The area is substantially the same as the size of the carbon nanotube array. The thickness of the carbon nanotubes is related to the height of the carbon nanotube array and the pressure of the rolling, which may be between 0.5 nm and 100 microns. It is understood that the greater the height of the carbon nanotube array and the lower the pressure applied, the greater the thickness of the prepared carbon nanotube rolled film; conversely, the smaller the height of the carbon nanotube array, the greater the applied pressure The smaller the thickness of the prepared carbon nanotube rolled film, the gap between the adjacent carbon nanotubes in the carbon nanotube rolled film, so that the carbon nanotube film is laminated on the carbon nanotube Forming a plurality of gaps or micropores having a size between 1 nm and 500 nm.

The plurality of carbon nanotubes are arranged in a preferred orientation along the length of the carbon nanotube film. The preferred orientation refers to the fact that most of the carbon nanotubes extend substantially in the same direction in the carbon nanotube film 099122581 Form No. A0101 Page 8 of 37 0992039783-0 201202319. And the overall extension direction of the majority of the carbon nanotubes is substantially parallel to the surface of the nanocarbon S. Further, most of the carbon nanotubes in the carbon nanotube film are connected end to end by van der Waals force. Specifically, in the nano carbon tube film, each of the majority of the carbon nanotubes extending substantially in the same direction

direction by van der Waals. Of course, there are a few carbon nanotubes in the carbon nanotube film that deviate from the X direction. These carbon nanotubes do not form the overall orientation of most of the carbon nanotubes in the carbon nanotube film. Significant impact. The self-supporting carbon nanotube film does not require a large-area carrier support, but only provides a shearing force to the internal phantom state, that is, the nano carbon tube is placed (or Fixed to the interval - when the distance between the two supports is set, the π-meter broken film between the two branches can be suspended to maintain its own film state. The self-supporting building mainly passes through the carbon nanotubes. There are continuous carbon nanotubes in the film which are continuously arranged by van der Waals. Specifically, the majority of the carbon nanotubes extending substantially in the same direction in the nanocarbon S-drawing film are not absolutely linear, and may be appropriately bent: or may not be properly deviated in the direction of the extension. Extend the direction. Therefore, it is impossible to rule out that there may be partial contact between the carbon nanotubes juxtaposed in the majority of the carbon nanotubes extending substantially in the same direction. [0021] The non-slave film comprises a plurality of continuous and oriented carbon nanotube segments 6 which are first connected by van der Waals. Each of the carbon nanotube segments consists of a plurality of carbon nanotubes that are parallel to each other. The carbon nanotube segment has any length, thickness, and uniformity. 099122581 Form No. A0101 Page 9 of 37 0992039783-0 201202319 Shape. The carbon nanotube film has good light transmittance and the visible light transmittance can reach more than 75%. [0022] When the carbon nanotube structure comprises a multi-layered carbon nanotube film, a preferred angle between the adjacent two layers of carbon nanotube film forming an intersection angle α, α Greater than or equal to 0 degrees and less than or equal to 90 degrees (0° α 90°). Referring to FIG. 4, preferably, in order to increase the strength of the carbon nanotube film, the intersection angle α is approximately 90 degrees, that is, the arrangement of the carbon nanotubes in the adjacent two layers of carbon nanotube film. The direction is substantially vertical to form a cross film. a gap between the plurality of carbon nanotube membranes or between adjacent carbon nanotubes in a carbon nanotube membrane, thereby forming a plurality of uniform distributions in the carbon nanotube structure, Arranged randomly, with a size between 1 nm and 500 nm or micropores. [0023] The carbon nanotube structure may include at least one nanocarbon line structure. When the carbon nanotube structure includes a plurality of nanocarbon line structures, the plurality of nanocarbon line structures may be disposed in parallel, wound or woven with each other. The carbon nanotube line includes at least one nanocarbon line. When the nanocarbon line structure comprises a plurality of nanocarbon lines, the individual carbon carbon lines are intertwined or arranged in parallel, and the plurality of nanocarbon lines are combined by van der Waals. [0024] The nano carbon pipeline may be a linear structure formed by processing a carbon nanotube film, and the treatment method of the carbon nanotube film includes a volatile organic solvent infiltration treatment or mechanical torsion treatment. . The volatile organic solvent infiltration treatment may immerse the organic solvent on the surface of the carbon nanotube film by a test tube to infiltrate the entire carbon nanotube film, or the above-mentioned fixed frame formed with the carbon nanotube film may be formed. The whole is immersed in a container containing an organic solvent to infiltrate. The volatile organic solvent is ethanol, decyl alcohol, acetone, dichloro 099122581 Form No. 1010101 Page 10 / Total 37 Page 0992039783-0 Ethylene or gas imitation 'In this example, ethanol nano __ is used to form a nano carbon pipeline It includes a plurality of carbon tubes arranged along the length of the nanocarbon pipeline. With the ship, the _ turn of the nano carbon pipeline includes = carbon tube through the end of the red force of the end of the eye and along the tube _ to the preferred 2 row 1. The material used in the remnant of the money is twisted by the thief force to twist the ends of the navel stone film in opposite directions. Referring to FIG. 6 and FIG. 7 , the nano carbon line is a twisted nano carbon pipeline by mechanical twist reduction. The twisted nano carbon pipeline includes a plurality of nanowires arranged in an axial spiral arrangement. Carbon nanotubes. Specifically, the (four) turn-by-nano carbon pipeline includes a plurality of naitree tubes, and the rails are end-to-end connected to the nanocarbon pipeline and extend axially in a spiral shape. It will be appreciated that the obtained nanocarbon tube may also be subjected to a volatile organic solvent wetting treatment or a mechanical torsion treatment simultaneously or sequentially to obtain a twisted nanocarbon line. Please refer to Fig. 8 and Fig. 9 for the shrinkage and torsion-nano carbon pipeline obtained by sequentially mechanically twisting the carbon nanotube film and treating the volatile organic solvent. After the polymer is infiltrated into the carbon nanotube structure, it is combined with the carbon nanotube to form the carbon nanotube composite structure. Since the contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees, the polymer dissolved in the organic solvent can be infiltrated together with the organic solvent in the carbon nanotube structure and the carbon nanotubes are tight. Combine 'to obtain a carbon nanotube composite structure with excellent mechanical properties. The preparation method of the carbon nanotube composite structure may further include the following Form No. A0101 Page 11 of 37 0992039783-0 201202319 Step: S30, the polymer-infiltrated carbon nanotube structure is dried. [0027] In step S30, the organic solvent in the polymer-impregnated carbon nanotube structure is removed, thereby obtaining the organic solvent-free carbon nanotube composite structure. 5度。 The mass percentage of the polymer in the carbon nanotube composite structure is approximately at 2.5 ° /. Between 21.5%. The manner of drying the polymer-infiltrated carbon nanotube structure is not limited, and it may be carried out by natural air drying or by heater drying without merely oxidizing the polymer. [0028] A method for preparing a carbon nanotube composite structure according to a second embodiment of the present invention includes the following steps: [0029] S110, dissolving a polymer monomer in an organic solvent to form a polymer monomer solution, The contact angle of the organic solvent to the carbon nanotubes is less than 90 degrees> [0030] S120, a nanocarbon pipeline structure having a self-supporting structure is impregnated in the polymer monomer solution; and [0031] S130, The polymer monomers in the polymer monomer solution polymerize with each other to form a polymer and are combined with the nanocarbon line structure. [0032] In step S110, the polymer monomer includes any one or a combination of acrylonitrile, vinyl alcohol, propylene, styrene, ethylene ethylene or ethylene terephthalate. [0033] The preparation method of the carbon nanotube composite structure provided by the embodiment of the present invention is basically similar to the steps and principles of the preparation method of the carbon nanotube composite structure provided by the first embodiment of the present invention, and the main difference is that the The polymer is infiltrated in the structure of the carbon nanotubes by in-situ polymerization, ie 099122581 Form No. A0101 Page 12 / Total 37 Page 0992039783-0 201202319 [0034] Ο [0035] Ο [0036] 099122581 By Step 5120 And the magic step 3 to complete the functions performed by the S2G step in the first embodiment of the present invention. Since in the same - organic solvent, the polymerization. The solubility of the monomer is greater than the degree of resolution of the polymer formed by polymerization of the polymer monomer. Therefore, it is possible to selectively dissolve the erroneous polymer in the organic solvent to recombine with the carbon nanotube structure, and only the corresponding polymer. The solubility of the precursor in the organic spray may be good. The aggregation can be made. The selection of the material is broader, that is, the carbon nanotube film structure can be infiltrated with a polymer which is insoluble in the organic solvent. In order to more clearly illustrate the preparation method of the carbon nanotube composite structure of the present invention, the specific method will be described below. For the structure of the carbon nanotube film line or other cities, the treatment methods are relatively similar. The specific embodiment is described by taking the twisted carbon nanotube line in the carbon nanotube line as an example. First, the polyvinyl alcohol is dissolved in a dimethyl sulfoxide solution to form a polyvinyl alcohol solution. The degree of polymerization of the polyethylene is between m (four). The contact angle of the dimethyl subdomain to the carbon nanotubes is approximately 7 ,, and the surface tension of the dimethyl soil is approximately 43·45 mA. The mass percentage of the polyethylene glycol in the polyvinyl alcohol broth or the concentration of the polyethylene glycol solution is approximately between 1%. Preferably, the polyvinyl alcohol is substantially 5% by mass in the polyvinyl alcohol & solution, so that the polyvinyl alcohol can fill the twisted nanocarbon pipeline and utilize the surface thereof. The tension is pulled closer to the distance between the carbon nanotubes in the nanocarbon line, thereby minimizing the twisted nano-breaking line to obtain a nano carbon line having a large strength. Next, the twisted nanocarbon line of FIG. 6 is infiltrated into the alcohol solution in the polyethylene form number Α0101, page 13 of 37, 0992039783-0 201202319, and the polyvinyl alcohol and the twisted nephew The carbon carbon line is infiltrated to form a composite line of carbon nanotubes as shown in Figs. 10 and 11 . [0037] comparing FIG. 6, FIG. 8 and FIG. 10, and FIG. 7, FIG. 9 and FIG. 11, the carbon nanotube composite line is opposite to the twisted nanocarbon pipeline and the contracted and twisted nanocarbon pipeline, although Both are based on the same carbon nanotube structure, but after treatment, the diameter and density are different. The carbon nanotubes of the carbon nanotube composite wire have a smaller diameter and a higher density, and the gap between the carbon nanotubes is substantially filled with polyvinyl alcohol. Referring to FIG. 12, the diameters of the twisted nanocarbon pipeline of FIG. 6, the contracted and twisted nanocarbon pipeline of FIG. 8, and the nanocarbon tube composite line of FIG. 10 are respectively obtained, and the axial direction resistance is obtained. Tensile strength and Tensile load. It can be seen from the figure that the twisted carbon nanotubes have a significant improvement in tensile strength and tensile load after being composited to form a carbon nanotube composite wire. Further, please refer to FIG. 13 , which is a tensile-strain comparison diagram of the twisted nanocarbon pipeline of FIG. 6 , the contracted and twisted nanocarbon pipeline of FIG. 8 , and the carbon nanotube composite wire of FIG. 10 . It can be seen from the figure that after the twisted carbon nanotubes are composited to form a carbon nanotube composite wire, under the same strain, the tensile strength of the carbon nanotube composite wire is greater than that of the twisted nanocarbon pipeline. And the tensile strength of the contracted and twisted nanocarbon line. Thus, it can be explained that the carbon nanotube composite structure having a large tensile strength, a large tensile load, and a large tensile strength/strain ratio can be obtained by the preparation method of the carbon nanotube structure. [0038] Please refer to FIG. 14 , which is a comparison diagram of tensile strength obtained when the carbon nanotube composite wire is formed in different concentrations of polyvinyl alcohol solution. As can be seen from the figure, the tensile strength of the carbon nanotube composite wire is related to the concentration of the solution of the polyvinyl alcohol 099122581 Form No. A0101, page 14 / 37 pages 0992039783-0 201202319, when the polyethylene When the mass percentage of the alcohol in the polyvinyl alcohol solution is approximately 5% or the concentration of the polyethene alcohol solution is about 5%, the nano carbon tube composite wire has the highest tensile strength and can reach 2 GPa. 2克帕。 However, the tensile strength of the carbon nanotube composite wire is greater than 1. 2G Pa. Ο Refer to FIG. 15 ′ for the tensile load and diameter comparison diagrams obtained when the carbon nanotube composite wire is formed in different concentrations of polyvinyl alcohol solution. As can be seen from the figure, when the concentration of the polymer is approximately 5%, the diameter of the carbon nanotube composite wire is the smallest 'the tensile load is the largest. Please refer to Figure 16 for a comparison of the tensile strength and diameter of the Zener carbon nanotube composite wire formed at different temperatures of the polyethylene glycol solution. It can be seen from the figure that although the diameter of the carbon nanotube composite wire increases with the increase of temperature, the tensile strength decreases, but the tensile strength changes less than 50 degrees, which is better. Temperature stability. And because of the low level of spill required in the production department, it is advantageous for mass production. [0040] FIG. 17 is a schematic view showing the tensile strength of a carbon nanotube composite wire composed of a carbon nanotube of 425 micrometers and 250 micrometers, respectively, at different straight and light temperatures. It can be seen from the figure that the tensile strength of the carbon nanotube composite wire composed of carbon nanotubes of different lengths from 4 micrometers to 24 micrometers is greater than that of 丨.5 (; [0041] In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
