Abstract:
The present disclosure relates to a method for making a transparent carbon nanotube composite film. The method includes: (a) providing a transparent carbon nanotube film structure; (b) fixing the transparent carbon nanotube film structure on a supporting; (c) immersing the transparent carbon nanotube film structure with the supporting into a transparent polymer solution; and (d) removing the transparent carbon nanotube film structure with the supporting from the transparent polymer solution, thereby forming the transparent carbon nanotube composite film. A light transmittance of the transparent carbon nanotube composite film structure is higher than a light transmittance of the transparent carbon nanotube film structure.
