In addition, due to the shortcomings of the mechanical and chemical durability of the Tings layer and the uneven distribution of the resistance of the transparent conductive layer, the performance of the prior electronic components is not good. In view of this, it is indeed necessary to provide an electronic component having a low cost, excellent mechanical properties, uniform resistance distribution, and good light transmission.

The second and third tube layers have a relatively uniform structure, so the nanometer ._ ^ has a uniform resistance, thereby improving the performance of the snow. The third embodiment is because the carbon nanotube screen of the present technical solution can be laid as a transparent conductive layer without sputtering and heating, thereby reducing the manufacturing cost of the electronic component. ”, [Embodiment]

Using a stretching tool to pull from the carbon nanotube array to obtain a carbon nanotube film. Specifically, the method includes the following steps: ") selecting a plurality of carbon nanotube segments of a predetermined width from the carbon nanotube array, and the embodiment preferably adopts a tape having a constant width to contact the carbon nanotube array to select a certain a plurality of carbon nanotube segments of a width; (1) stretching the plurality of carbon nanotube segments at a rate substantially perpendicular to the growth direction of the carbon nanotube array to form a continuous carbon nanotube film. Excessively, the plurality of carbon nanotube segments are gradually separated from the substrate by the tensile force in the direction of stretching, and the selected plurality of carbon nanotube segments are respectively associated with the other carbon nanotubes due to the van der Waals force. Fragment 200927690 The appendix is continuously pulled out continuously to form a film of carbon nanotubes. The: Meteorite & film comprises a plurality of carbon nanotube bundles connected end to end and oriented. The carbon nanotubes The film is arranged such that the arrangement direction of the carbon nanotubes is substantially parallel to the stretching direction of the carbon nanotube film. Step 3: preparing the two carbon nanotube films described above, and overlapping and intersecting each other to form a transparent conductive layer 24. preparation Two carbon nanotube films, each of which is a carbon nanotube layer. The two carbon nanotube layers are overlapped, so that the two carbon nanotube layers are The aligned carbon nanotubes have an intersection angle α, such as 9〇. It can be understood that the arrangement direction of the carbon nanotubes in the carbon nanotube film is substantially parallel to the stretching direction of the carbon nanotube film. Therefore, the carbon nanotubes between the two carbon nanotube layers can be set at an intersection angle α. Referring to FIG. 3, the carbon nanotube film is a plurality of carbon nanotube bundles arranged in a preferred orientation. The carbon nanotube film having a certain width formed by the end-to-end connection. The arrangement direction of the carbon nanotubes in the carbon nanotube film is substantially parallel to the stretching direction of the carbon nanotube film. The preferred orientation obtained by the direct stretching is two. The carbon nanotube film has better uniformity than the disordered carbon nanotube film, that is, has a more uniform thickness and has uniform electrical conductivity. At the same time, the method of directly stretching the carbon nanotube film is simple. Fast and suitable for industrial application & 'Using the carbon nanotube layer of the present technology as the transparent conductive Jen 24' can reduce the fabrication of the electronic component 20. It can be understood that the Huimi carbon tube in the super-sequential carbon nanotube array of this embodiment is very Pure' and because the specific surface area of the carbon nanotube itself is not large, the carbon film itself has a strong dryness. Therefore, the carbon nanotube film formed by the present embodiment forms a carbon nanotube layer. And as the transparent conductive layer 24, it can be directly (four) on the surface of the substrate 22. An additional 'the organic solvent can be used to treat the above-mentioned carbon nanotube layer adhered to the substrate 22', which can be organically The solvent is dripped on the surface of the nano carbon layer and the entire carbon nanotube layer is moistened. The organic solvent is a volatile organic solvent such as ethanol, alcohol, acetone, dichloroethane or chloroform, which is known in the present embodiment. Use ethanol. After the carbon nanotube film is infiltrated by the organic solvent, the surface tension of the volatile organic solvent is made, and the parallel carbon nanotube segments in the carbon nanotube film are partially aggregated into the carbon nanotube bundle, so The non-carbon carbon thin crucible has a small surface volume ratio, m and good mechanical strength and toughness. Further, at least two electrodes 26 may be disposed on one surface of the transparent conductive layer 24 according to actual needs. Preferably, the at least two electrodes 26 are spaced apart from each other on a surface of the transparent conductive layer 24 away from the substrate 22. It can be understood that the above-mentioned electrodes 26 can also be disposed on different surfaces of the transparent conductive layer 24, and the key is to ensure that the above-mentioned electrode 26 and the transparent conductive layer 24 are electrically connected. The material of at least two of the above electrodes may be a long line of copper, silver, gold, graphite or carbon nanotubes. Specifically, in the present invention, the intermediate substrate 22 is a glass substrate, and the at least two electrodes are strip electrodes composed of a mirror layer or a box of copper. The electrode % can be sputter-plated, chemically bonded, or the like. The deposition method is directly formed on the transparent conductive layer 24. Alternatively, the at least two electrodes 26 may be bonded to the transparent conductive layer 24 by a conductive adhesive such as silver paste. 12 200927690 It is understood that the electrons provided in the present technical solution can be understood. The transparent conductive layer 24 of the component 20 is formed by photolithography or laser (4). After forming the money, the electronic component 20 can be used as a transparent electrode or circuit for planar display, photoelectric, touch screen, electroluminescence and electromagnetic shielding ( Specifically, when used as a heat source, the electronic component 2 can include two electrodes. The two electrodes described above are spaced apart from each other on the surface of the transparent conductive layer % away from the substrate 22. The above two After the electrodes are respectively connected to the wires, the power is connected. Since the two electrodes are arranged at a certain distance, a certain resistance is connected to the transparent conductive layer 24 between the two electrodes. The value prevents the occurrence of a short circuit phenomenon. Therefore, when the power source is connected, the transparent conductive layer 24 of the electronic component 2 can emit electromagnetic waves of a certain wavelength range. When used for a touch screen, the electronic component 20 can include four electrodes. The above four electrodes are spaced apart on one surface of the transparent conductive layer 24 away from the base 22. The above four electrodes are respectively connected to the wires and connected to the power source. Since the above four electrodes are spaced apart by a certain distance, the transparent conductive The layer 24 includes a carbon nanotube layer, and the carbon nanotubes in the carbon nanotube layer are ordered: the column, so that the transparent conductive layer 24 has a uniform resistance distribution. Therefore, after the power supply, the transparent The equipotential surface of the uniform layer is formed on the conductive layer 24. When a touch object such as a hand or a conductive pen is close to or close to the transparent conductive sonar, a coupling capacitor is formed between the touch object and the transparent conductive layer 24; In terms of frequency current, the capacitor is a direct conductor, so the finger sucks a part of the current from the contact point. This current flows from the electrode on the touch screen 2〇 and flows through the four electrodes. The distance from the finger to the four corners is positive. The touch screen controller obtains the position of the touch point by accurately calculating the ratio of the four currents. The electronic component 20 provided by the embodiment of the present technical solution has the following advantages: The carbon nanotube layer has good tensile strength and mechanical strength. Therefore, the use of a carbon nanotube layer as the transparent conductive layer 24 can improve the durability of the electronic component. Second, because the carbon nanotube layer has a comparative The structure of the average sentence, therefore, the use of a carbon nanotube layer as the transparent conductive layer 24, the transparent conductive layer can have a uniform electrical resistance, thereby improving the performance of electronic components. Third, due to the carbon nanotube layer of the technical solution It can be directly laid as a transparent conductive layer, and there is no need for sputtering and heating processes, so the manufacturing cost of electronic components is reduced.
