GRAPHENE TRANSPARENT CONDUCTIVE FILM

摘要

A graphene transparent conductive film, Which includes a plurality of graphene sheets and a transparent conductive binder binding the graphene sheets to form the graphene transparent conductive film. The weight ratio of the graphene sheets to the transparent conductive binder is within a range of 0.01 to 1 wt %, and the volume percentage of the transparent conductive binder in the graphene transparent conductive film is within a range of 0.5 to 10%. The transparent conductive binder is a transparent conductive polymer comprising at least one structure of polythiophene and polycationic polymer. The graphene sheets are stacked and bound together by the transparent conductive binder to form the integrated conductive network structure such that the resulting graphene transparent conductive film still has lower sheet resistance with high transparency. Therefore, the present invention can be formed on the flexible support body and greatly expand the field of application.
