▎ 摘  要

NOVELTY - Im-situ of graphene coating by reducing graphene oxide by friction in inert environment involves dispersing graphene oxide ultrasonically in a volatile solvent and spraying it on the surface of the substrate to form a graphene oxide coating. In an inert environment, a friction pair with chemically active bonds is used, and positive pressure is applied to perform dry friction on the surface of the graphene oxide coating to form a perfect structure of graphite in situ on the friction slip track. USE - Method for in-situ preparation of graphene coating by reducing graphene oxide by friction in inert environment. ADVANTAGE - The method enables in-situ preparation of graphene coating by reducing graphene oxide by friction in inert environment exhibits excellent lubricating properties.
