SURFACE GRAPHENIZATION OF A METALLIC OR METALLIZED REINFORCEMENT BY FLAME SPRAY PYROLYSIS

摘要

Process for depositing graphene on the run on the surface (17) of a metallic or metallized continuous reinforcement (R), positioned at the periphery of which is a surface metal layer (Ms) selected from copper, nickel and copper-nickel alloys, said process comprising at least one step of flame spray pyrolysis (FSP), under a reducing atmosphere (13), of a precursor of carbon that generates in the flame at least one carbon-containing gas such as carbon monoxide, which is sprayed on the surface (17) of the reinforcement while running, and decomposes thereon to form one or more layers of graphene at the surface of the surface metal; an additional step of functionalization of the graphene makes it possible to adhere the reinforcement to a polymer matrix such as a rubber matrix.
