Abstract
An electrical conducting polymer is prepared from carbon nanotubes and polymer in weight ratio of 1: (2-1000) through preparing carbon nanotube suspension, preparing polymer solution, mixing and moulding.
Description
Technical Field
The present invention relates to a conductive polymer and a method for preparing the same, and more particularly, to a conductive polymer containing carbon nanotubes and a method for preparing the same.
Background
The carbon nanotube is one new kind of carbon structure material, and is especially one kind of tubular structure matter with diameter of several nanometers and length of several microns. Due to the unique structure, the material has many excellent performances incomparable with other materials, such as unique conductor or semiconductor conductivity, extremely high mechanical strength, hydrogen storage capacity, microwave absorption capacity and the like.
With the rapid development of modern technology, the harm and potential harm to human beings caused by electromagnetic wave radiation are increasingly enhanced, and the high-performance conductive polymer can improve the electromagnetic interference resistance of electronic equipment, inhibit electromagnetic radiation and realize EMI electromagnetic wave shielding, and is widely applied to the plastic shells or the inner parts of cases of electronic equipment such as mobile phones, computers, medical instruments, information appliances, aerospace and the like.
Since the end of the 80 s, research work on conductive polymers began, but due to various conditions, no technology and products suitable for market needs were available yet. Since the invention of carbon nanotubes, they have been developed for use as additives in conductive polymers by virtue of their excellent conductivity properties. At present, in some scientific researches, a hot melting method is generally used for processing a polymer material, but mechanical stirring is adopted, so that the added carbon nanotubes are easily broken, particularly when a hot-melt high polymer material becomes viscous by heating, the carbon nanotubes are easily broken during stirring, and the broken carbon nanotubes lose excellent electric conductivity.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a conductive polymer with good conductive performance, simple preparation process and low cost and a preparation method thereof.
The purpose of the invention can be realized by the following technical scheme:
the conductive polymer is characterized by comprising carbon nanotubes and a polymer material, wherein the weight ratio of the carbon nanotubes to the polymer material is 1: 2-1000.
The carbon nano-tube is selected from one or a mixture of two of single-wall carbon nano-tube or multi-wall carbon nano-tube.
The polymer material comprises one or a mixture of more of polycarbonate, polyacrylate and polyethylene copolymer.
The structural formula of the polycarbonate polymer material is as follows:
said
R1＝-H；-F；
R2＝-CH3；-CH2CH3；-CH2CH2CH3；-CH(CH3)CH3；
n＝100～4000。

n＝100～10000。
The structural formula of the polyethylene copolymer is as follows:
said
R1，R2，R3，R5，R6，R7＝-H；
R4，R8＝-C6H5；-CN；-Cl；-COOCH3；-COOCH2CH3
n＝100～10000；
m＝100～10000。
A method for preparing a conductive polymer, comprising the steps of:
(1) dissolving carbon nanotubes with average diameter of 1.0-10 nm and length of more than 1 mu m in an organic solvent at a concentration of 0.1-10 mg/ml, and stirring and dispersing to prepare a uniform suspension A;
(2) adding a polymer material with the average particle size of 1-15 mm into an organic solvent to prepare a uniform solution B at the concentration of 5-200 mg/ml;
(3) and mixing the suspension A into the solution B, wherein the weight ratio of the carbon nano tube to the polymer material is 1: 2-1000, uniformly mixing, and pouring into a mold for molding to obtain the conductive polymer.
The organic solvent is selected from one or a mixture of several of methanol, ethanol, propanol, isopropanol, butanol, 1, 2-ethylene glycol, 1, 3-propylene glycol, glycerol, dichloromethane, chloroform, carbon tetrachloride, 1, 2-dichloroethane, 1, 1, 1-trichloroethane, acetic acid, propionic acid, butyric acid, succinic acid, valeric acid, acetone, 3-pentanone, cyclopentanone, cycloethanone, methyl acetate, ethyl acetate, propyl acetate, diethyl ether, dioxane, tetrahydrofuran, petroleum ether, pentane, ethane, cyclohexane, heptane, formamide, acetamide, N, N-dimethylformamide, benzene, toluene, xylene, pyridine, pyrrole and pyrazole.
The invention adopts a dissolution method to prepare the conductive polymer, namely, the high molecular polymer material is reduced in viscosity by adding the organic solvent, and the carbon nano tube is not easy to be damaged when the carbon nano tube is added into the high molecular polymer material, so that the conductive polymer containing the carbon nano tube with excellent performance is prepared, the conductive capability is greatly improved, and the wide application prospect is developed.
Compared with the prior art, the invention has the following advantages:
(1) the percolation Threshold of the conductive polymer is greatly reduced. This value is added to the polymer in relation to the shape of the additive, the larger the aspect ratio, the lower the P value; below the P value, the material is insulating, above the P value, the material begins to conduct; the additive is of a spherical structure, and the P value appears at about 20-30% by weight. In the case of tubular additives, the P value theoretically occurs at a weight content of < 1%, in practice around 1%. The lower the P value, the better the material performance, since the original properties of the polymer material can be influenced less and the more additives, the more difficult the reprocessing.
(2) The performance of the conductive polymer added with the carbon nano tube is much higher than that of the conductive polymer using other additives at present, the additives usually adopted at present are carbon black and the like, and the conductive capability of the polymer using the carbon nano tube is improved by three orders of magnitude compared with that of the polymer using the carbon black. Meanwhile, the product obtained by the method (dissolution method) has the conductivity which is much higher than that of the product obtained by the existing hot melting method.
(3) The conductive polymer material using the carbon nanotube as the additive is easier to process and has less damage to the grinding tool than the conductive polymer material using other materials as the additive. For example, when a polymer mobile phone case made of steel fibers as additives is processed, the damage degree to the grinding tool is large.
(4) The composite material using the carbon nanotube as the additive is more uniform than the composite material using the steel fiber, so that the composite material can be precisely processed, thereby opening the application prospect in the field of electronics.
(5) The preparation process is simpler than the hot melting method, and the preparation method is easy to process and low in cost.
