▎ 摘 要
NOVELTY - Reduction modification of graphene oxide (GO) and preparation of different protective layer structures comprises mixing polyvinyl butyral (PVB), polydimethylsiloxane (PDMS) prepolymer and absolute ethanol to obtain PVB paint, spin coating PVB paint on metal substrate as first layer of protective coating, adding aqueous polyurethane to mixed solution of GO and Vitamin C and spraying on the surface of heated PVB with spray gun as second layer of protective coating. USE - The method is for reduction modification of graphene oxide and preparation of different protective layer structures. ADVANTAGE - The method is simple and easy to operate.
