(1) Preparing a carbon nanotube film. - the carbon nanotube film is an ordered carbon nanotube film or a disordered carbon nanotube thin film, which can be obtained by a rolling method, a flocculation method, or directly from a carbon nanotube array Pull to get. Preferably, in the present embodiment, the carbon nanotube film is obtained by directly pulling the obtained carbon nanotube film structure from the carbon nanotube array. The method for fabricating the nanocarbon f-film structure specifically includes the following steps: First, an array of carbon nanotubes is provided. 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 nano-small reverse array, a double-walled carbon nanotube array, and a multi-walled carbon nanotube array. The embodiment of the present invention, the method for preparing the super-sequential carbon nanotube array, the chemical vapor deposition method for the eucalyptus, the specific steps comprising: (&) providing a flat substrate, the substrate can be selected from p-type or N-type 矽The substrate, or the germanium substrate formed with the oxide layer, is preferably a 4-inch germanium substrate; (b) a catalyst layer is uniformly formed on the surface of the substrate, and the catalyst layer material may be iron (Fe) or cobalt (c). 〇), nickel (Ni) or any of the alloys of the combination thereof; (c) annealing the substrate on which the catalyst layer is formed in air of 7CKTC to 900aC for about 30 minutes to 9 minutes; (d) • The treated substrate is placed in a reaction furnace, heated to 500 ° C to 740 ° C in a protective gas atmosphere, and then passed through a carbon source gas for about 5 to 3 minutes to grow to obtain a super-sequential carbon nanotube array. Its height is 5 〇 microns ~ 5 mm. The super-sequential carbon nanotube array is a plurality of pure carbon nanotube arrays formed of carbon nanotubes that are parallel to each other and perpendicular to the substrate. Through the above control and growth conditions, the super-sequential carbon nanotube array contains substantially no impurities such as amorphous carbon or residual catalyst metal particles. The carbon nanotubes in the array of carbon nanotubes form an array by close contact with each other by van der Waals force. The carbon nanotube array is substantially the same area as the above substrate. In this embodiment, the carbon source gas may be a chemically active hydrogen absorbing compound such as acetylene, ethylene or methane. The preferred carbon source gas in this embodiment is acetylene, and the argon gas is nitrogen or an inert gas, which is preferred in this embodiment. The gas is argon. It is understood that the carbon nanotube array provided in the present embodiment is not limited to the above production method. It can also be a graphite electrode constant current arc discharge deposition method, a laser evaporation deposition method, or the like. Too, and secondly, a draw tool was used to pull a nanotube film structure from the carbon nanotube array. Specifically, the method comprises the following steps: (a) selecting a portion of the carbon nanotubes from the neva 2 anti-s array, and in this embodiment, preferably: using a tape of a predetermined width to contact the array of carbon nanotubes to select a portion of the nano-gauge, (b) stretching the portion of the nanocarbon at a rate substantially perpendicular to the growth direction of the carbon nanotube array; and elevating a continuous carbon nanotube to pull the 201003488 membrane structure. During the above stretching process, the part of the carbon nanotubes under the tensile force: the stretching direction is gradually separated from the substrate, due to the van der Waals:: other in the tube array; the carbon nanotubes of the f and the nanometer respectively The carbon-free stone is continuously pulled out in the opposite direction of the ear, and forms a nano carbon camp; ^^ * pull film... structure. The width of the carbon nanotube film structure and the width and height of the carbon nanotube array are related to each other. The width of the nano carbon film structure is 2 G PCT*, and the thickness is 〇5 nm to 100 μm. . · b) The above-mentioned carbon nanotube film is treated by laser. Because of the existence of the vanadium in the carbon nanotube film itself, some of the carbon nanotubes of the nanotube film t are easy to aggregate, and the carbon nanotube bundle is larger. , affecting the conductivity of the carbon nanotube film 4 . In order to improve the light transmittance of the carbon nanotube film, the carbon nanotube film is irradiated with a laser having a power density of more than o.ixio 4 watt/m 2 to remove the poorly transmissive carbon nanotube bundle in the naphthalene film. The step of treating the nano carbon official film by laser can be carried out in an oxygen-containing environment, preferably in an air atmosphere. The above-mentioned carbon nanotube film can be fixed by laser treatment, and then the carbon nanotube film is fixed by moving the laser device, or the carbon nanotube film is moved by a solid-state laser device to make the mine The method of irradiating the carbon nanotube film is achieved. In the above process of laser irradiation of the carbon nanotube film, since the carbon nanotube has good absorption characteristics for the laser, the laser is a higher energy 18 201003488 ^ which is absorbed by the carbon nanotube film. The heat that causes the carbon nanotubes in the nanocarbon:: membrane to heat up. In the carbon nanotube film, the carbon nanotubes of the small carbon nanotubes are directly absorbed by the large carbon nanotube bundles, so the temperature of the carbon nanotubes in the carbon nanotube bundle is higher. The temperature of the carbon tube: = enough south (generally greater than _. 〇, the carbon nanotube bundle is burned by the laser. The heart is shown in Figure 7 and Figure 8 relative to the carbon nanotube film before the laser treatment. Laser The light transmittance of the treated carbon nanotube film is remarkably improved, and the light transmittance thereof is more than 70%. It is understood that the purpose of using the laser treatment of the carbon nanotube film structure is to further improve the carbon nanotube film. The transparency of the structure, so this step is an optional step. (4) The surface of the polymer material solution on the at least the nano-carbon film is formed into a carbon nanotube base.

When the carbon nanotube film 224 reaches the lower portion of the underwind device 216, the wind blown by the blowing device 216 applies a certain pressure to the carbon nanotube film 224, so that the nano-carboniferous film 224 is immersed in the layer 226 of the molecular material, that is, the polymer material. The carbon nanotube film 224 is infiltrated and then passed through the tube furnace 212. The high temperature inside the tube furnace 212 solidifies the polymer material infiltrated into the carbon nanotube film 224, forming a nanometer on the surface of the flexible substrate 218. Carbon tube composite layer 228. (iv) The flexible substrate 218 on which the carbon nanotube composite material layer 228 is formed is cut to form an electrode plate. Progressively, a plurality of first electrodes or second electrode plates can be formed by arranging two electrodes at the surface of the carbon nanotube composite layer 228. The polymer material solution is coated on the upper substrate, so that the substrate can be continuously produced in the surface of the substrate (4) to improve the production efficiency, save operating time, and further save 24 201003488.
