Preferably, the array is a super-sequential carbon nanotube array. The carbon nanotube array provided by the embodiment of the present technical solution is one or more of a single-walled carbon nanotube array, a double-walled carbon nanotube array, and a multi-walled carbon nanotube array. In this embodiment, the method for preparing the super-sequential carbon nanotube array adopts a chemical vapor deposition method, and the specific steps thereof include: providing a 7-level substrate, the substrate may be a P-type or N-type germanium substrate, or may be selected to form The ruthenium substrate having an oxide layer is preferably a 4-inch ruthenium substrate in this embodiment; (b) a catalyst layer is uniformly formed on the surface of the substrate, and the catalyst 16 1360768 agent layer material can be selected from iron (8), recorded (combined r L Α darts (m) or any of them 700. ~9 [c two substrates with a catalyst layer formed in a 00 c process gas annealing for about 3 minutes, minutes; (4) two 1 substrate placed in the reactor ten In the protective gas environment, add demon to the long r to:: then pass the carbon source gas reaction for about 5 to 30 minutes, and produce a super-shunned carbon nanotube array with a height of 5 〇 micro 2 aligning carbon nanotubes The array is a plurality of parallel to each other and perpendicular to the base member: the super-sequential carbon nanotube array is substantially free of impurities, ..., scorpion slaves or residual catalyst metal particles, etc. The carbon carbon of the total carbon I of the rice Tubes are closely tied to each other by Van der Valle: "Mich Carbon Tube Array with The substrate area is basically the same. Qualitative! The carbon source gas can be selected from the chemical, parent, and active hydrocarbons such as B, Ethylene, and Arole. The preferred carbon source gas in this embodiment is acetylene, and the shielding gas is nitrogen or The inert gas gas is argon gas. It can be understood that the carbon nanotube array provided in the present embodiment is not limited to the above preparation method. It can also be a graphite electrode constant current arc discharge deposition method, an evaporation deposition method, etc. A stretching tool is used to pull a carbon nanotube array to obtain a:Minuoguan film structure. The specific steps include the following steps: (a) 敎 partial carbon nanotubes from the above carbon nanotube array, the implementation Preferably, the tape having a certain width contacts the carbon nanotube array to select a portion of the carbon nanotube; (b) the portion of the nanocarbon is stretched at a constant speed along a direction substantially perpendicular to the growth of the carbon nanotube array 17 I360768 a tube to form a continuous carbon nanotube film structure. During the above stretching process, the portion of the carbon nanotube is gradually separated from the substrate in the stretching direction by the tensile force, and the van der Waals force The carbon nanotubes in a portion of the carbon nanotubes are continuously drawn end-to-end with the other carbon nanotubes in the nanocarbon array, respectively, from: forming a carbon nanotube film structure.

Since the nano-tube 18 1360768 has good absorption characteristics for the laser, and the laser is a light with higher energy, it is used by the nanometer. After absorption of the carbon tube film, a certain amount of heat is generated to heat the carbon nanotubes in the carbon carbon film. In the carbon nanotube film, in the carbon nanotube film, the larger diameter carbon nanotube bundle absorbs more heat, so the temperature of the carbon nanotube in the carbon nanotube bundle is higher, when the nanocarbon When the temperature of the tube is high enough (generally greater than 600. 〇' nano carbon tube bundle is burned by laser. See Figure 7 and Figure 8, compared to the carbon nanotube film before laser treatment. The light transmittance of the carbon nanotube film is significantly improved, and its light transmittance is more than 70%.

In this process, the polymer material solution 22 in the wide mouth container 208 is attached to the surface of the base 218 due to the second rotating shaft portion being located in the wide mouth crying (10); a polymer material solution 226 is formed on the surface of the base body 218. The holding, the 230 and the second rotating shaft 204 maintain a certain distance, when the height =: the thickness of the material solution 226 exceeds the distance, 'scraping the second two' two, so the scraping device 230 can make the polymer The thickness of the solution must be kept uniform. 23 1360768 (1) A super-sequential carbon nanotube array 222 is fixed on the stage 21, and a continuous neat is pulled out from the super-aligned carbon nanotube array 222 The rice stone reverse film structure 224, one end of the carbon nanotube film structure 224 is adhered to the polymer material layer 226 on the surface of the flexible substrate 218. The nanometer film 224 from the carbon nanotube array 222 After being pulled out, when the polymer material layer 226 is not in contact, the silicon carbon nanotube thin film 224 may be irradiated by laser light emitted from the laser 234 to improve the transparency of the carbon nanotube film 224. The irradiation mode and specific parameters As mentioned above. (2) Turn on the power to make the traction 214 pulls the flexible substrate 218, the polymer material layer 226 and the carbon nanotube film 224 in a direction parallel to the axial direction of the furnace 212 at a certain speed. When the carbon nanotube film 224 reaches the lower portion of the air knife 216, the air knife The wind blown by 216 exerts a certain pressure on the carbon nanotube thin tube 224, so that the carbon nanotube film 224 is immersed in the polymer material layer 226, that is, the polymer material penetrates into the carbon nanotube film, and then passes through the tube type. In the furnace 212, the high temperature inside the tube furnace 212 solidifies the polymer material infiltrated into the nanofilm 224, and the carbon nanotube composite layer 228 is formed on the surface of the flexible substrate 218.
