[0059] The present invention provides a method for preparing the above-mentioned touch screen 10, the preparation method comprising the following steps: (w10) providing a substrate with a surface; (w20) forming an adhesive layer to be cured on the surface of the substrate; (w30 ) providing at least one carbon nanotube film; (w40) laying the at least one carbon nanotube film on the surface of the substrate to form a carbon nanotube layer covering the adhesive layer to be cured (w50) applying a pressure to the carbon nanotube layer so that the carbon nanotube layer is partially embedded in the adhesive layer to be cured, and the surface roughness Ra of the carbon nanotube layer is less than or equal to 0.1 micron; (w60) curing the adhesive layer; (w70) forming electrodes.
[0060] see Figure 8 , the preparation method of the touch screen 10 specifically includes the following steps:
[0061] In step (w10), firstly, a substrate 12 having a surface 121 is provided. Secondly, t...
