▎ 摘　　要

NOVELTY - The method involves growing a graphene layer on a metal-catalyzed base (101), and coating a layer of polyamic acid solution on the graphene layer. A polyimide (PI) film is formed (102) by thermal curing. The metal-catalyzed base is removed (103) to obtain a graphene conductive film having the PI film. The surface of the PI film coated with a resist solution prior to removal of the metal-catalyzed base, and the resist solution is cured to form a protective optical layer, where the optical refractive index of the protective layer is equal to or less than the refractive index of the PI film. USE - Method for preparing a graphene conductive film for a flexible touch device. ADVANTAGE - The method allows the graphene conductive film to be obtained with improved yield and at low cost while eliminating the need for a graphene film transfer process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene conductive film. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of a method for preparing a graphene conductive film for a flexible touch device.
