Method of transferring carbon conductive film

Abstract

Disclosed is a method of transferring a carbon conductive film, including: providing a first substrate, and forming an inorganic oxide layer on a surface of the first substrate, wherein the inorganic oxide layer has a total surface energy of 30 mJ/m2 to 75 mJ/m2, and a dispersive surface energy to the total surface energy ratio of 0.4 to 0.8. A carbon dispersion is coated on the inorganic oxide layer, and then dried to form a carbon conductive film on the inorganic oxide layer. The carbon conductive film is dipped into a solvent to separate the carbon conductive film and the inorganic oxide layer. The separated carbon conductive film is attached to a second substrate, thereby transferring the carbon conductive film onto the second substrate.
