Method of making transparent conductive film
First Claim
1. A method of fabricating a transparent conductive film, comprising:
- preparing a carbon nanotube composite composition by blending carbon nanotubes in a solvent, and further adding a polymer binder, wherein the carbon nanotube composite composition comprises 0.05 to 1 part by weight of the polymer binder and 0.05 to 1 part by weight of carbon nanotubes, based on 100 parts by weight of the solvent;
coating the carbon nanotube composite composition on a base substrate to form a carbon nanotube composite film; and
acid-treating the carbon nanotube composite film to form a transparent electrode on the base substrate by dipping the carbon nanotube composite film in an acid solution having a pH in the range of −
1 to 3, followed by washing the carbon nanotube composite film with distilled water and drying the washed carbon nanotube composite film.

Abstract
Disclosed herein is a method of fabricating a transparent conductive film, including preparing a carbon nanotube composite composition by blending a carbon nanotube in a solvent; coating the carbon nanotube composite composition on a base substrate to form a carbon nanotube composite film, and acid-treating the carbon nanotube composite film by dipping the carbon nanotube composite film in an acid solution, followed by washing the carbon nanotube composite film with distilled water and drying the washed carbon nanotube composite film to form a transparent electrode on the base substrate. The transparent conductive film can have excellent conductivity, transparency and bending properties following acid treatment, so that it can be used in touch screens and transparent electrodes of foldable flat panel displays. Further, the carbon nanotube composite conductive film can have improved conductivity while maintaining transparency after acid treatment.
