Abstract

The invention relates to a method for realizing high-temperature rubber conduction by using vapor-phase deposited graphene, and belongs to the application field of graphene composite conductive materials. This technology uses the plasma enhanced vapor deposition (PECVD) method to deposit graphene film on the top layer of high-temperature rubber, and utilizes the electrical conductivity, flexibility and ductility of graphene to realize high-temperature rubber and graphite through the close combination of graphene and high-temperature rubber. When stretched or twisted, ene produces synchronous strain, which makes the rubber conductive in different forms, thereby changing the functional properties of electricity and stability. And this conductivity can exist stably under different shapes or temperature conditions, the effect is obvious, and the method is simple.
