Abstract

The invention relates to a method of achieving electric conduction on high-temperature rubber by using vapor deposition graphene and belongs to the field of application of graphene composite electricconductive materials. In the technical scheme, by means of plasma enhanced chemical vapor deposition (PECVD), a graphene film is deposited on the most upper layer of the high-temperature rubber, so that by means of the electric conductivity, flexibility and ductility of the graphene and through tight combination between the graphene and the high-temperature rubber, synchronous strain of the graphene and the high-temperature rubber during tensioning or twisting is achieved. The rubber has electric conductivity in all forms, thus changing the functional characters in aspects of electricity, stability and the like; in addition, the electric conductivity is stable in all forms or at all temperature. The method has significant effect and is simple in process.
