▎ 摘　　要

NOVELTY - The film has a composite film body provided with a graphene thin film layer and a fibroin film layer. The graphene thin film layer is solidified on a surface of the fibroin film layer. USE - Graphene composite film for a conductive electrode (claimed). ADVANTAGE - The film has high photoelectric and transmission performances, heat conducting performance and flexibility. The film can be manufactured in a simple manner at less time with thin thickness. The film saves abundant raw material resources and adopts a fibroin substrate and a graphene conductive fill material to form the film body while processing. The film prevents the fibroin substrate from being damaged. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene composite film preparation method (2) a conductive electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a graphene composite film preparation method.'(Drawing includes non-English language text)' Step for preparing graphene thin film (1) Step for preparing fibroin film (2) Step for mixing graphene thin film and fibroin composite thin film (3)
