▎ 摘　　要

NOVELTY - Resin coating for coating on two sides of composite surfaces of substrate, comprises graphene and/or graphene oxide, where the substrate comprises multi-layer metal composites, metal/plastics composites, fiber composites (comprising carbon fibers and/or glass fibers), metal/fiber composites (comprising carbon fibers and/or glass fibers) and metal/ceramic composites. USE - The resin coating is useful for coating on two sides of composite surfaces of substrate. ADVANTAGE - The resin coating exhibits high tensile strength and barrier functionality.
