Abstract:
1. A method for making a touch panel, the method comprising the steps of: (a) providing a flexible substrate having a first surface; (a1) drawing at least two carbon nanotube films directly from a super-aligned carbon nanotube array; (b) applying a transparent carbon nanotube layer on the first surface of the flexible substrate, wherein the transparent carbon nanotube layer is formed by stacking the at least two carbon nanotube films, each of the at least two carbon nanotube films comprises a plurality of carbon nanotubes aligned substantially along a same direction and parallel to the first surface of the flexible substrate, the at least two carbon nanotube films are directly stacked with each other, and an angle is formed between the aligned directions of the carbon nanotubes in adjacent carbon nanotube films; (c) heat-pressing the transparent carbon nanotube layer on the flexible substrate; (d) locating two electrodes on opposite ends of the flexible substrate; (e) placing an insulative layer on edges of the first surface of the flexible substrate, the first surface having the transparent carbon nanotube layer formed thereon to form a first electrode plate; (h) repeating steps (a) to (e) to obtain a second electrode plate; and (f) securing the first electrode plate to the second electrode plate, with the insulative layer located between the first electrode plate and the second electrode plate, and wherein the transparent carbon nanotube layer of the first electrode plate is adjacent to the transparent carbon nanotube layer of the second electrode plate.
