▎ 摘  要

NOVELTY - Preparation of graphene surface coated silica composite material comprises mixing graphene, ammonia and silicon source, reacting, collecting product, and calcining. USE - The method is for preparation of graphene surface coated silica composite material used for anticorrosive coating with silane coupling agent (claimed). ADVANTAGE - The composite material has uniformly coated silica on surface of graphene which effectively isolate the contact between graphene in the coating and metal substrate and avoids galvanic corrosion, and better and improved anti-corrosion performance of the coating.
