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 is imparted with excellent conductivity, transparency and bending properties through acid treatment, so that it can be applied to touch screens and transparent electrodes of foldable flat panel displays. Further, the carbon nanotube composite conductive film has improved conductivity while maintaining transparency after acid treatment.
