NOVELTY - Complex conductive film comprises polymer substrate having surface coated with a mixture of graphene and metal ions mixed layer. USE - The complex conductive film is useful for electromagnetic shielding (claimed). ADVANTAGE - The material has high conductivity, flame retardance and simple preparation method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing complex conductive film comprising washing the high molecular polymer material substrate with alkali, modifying, conducting, coating the surface with graphene and metal ion mixed layer, purifying film, heat treating and subjecting the surface-coated graphene and the metal ion mixed layer to a plasma plating, complex plating and/or a coating plating.
