▎ 摘　　要

NOVELTY - Preparation of graphene oxide-coated modified microparticles involves dispersing fine particles in anhydrous ethanol, adding a silane coupling agent, heating, cooling, separating the resultant product to obtain coupling agent-modified particles, dispersing graphite oxide in water, obtaining a dubbed graphene solution, adding obtained solution to the coupling agent-modified particles, precipitating coupling agent-modified particles, separating and drying. USE - Preparation of graphene oxide-coated modified microparticles (claimed). ADVANTAGE - The method enables preparation of graphene oxide-coated modified microparticles by utilizing surface functional group of graphene oxide to uniformly coat on surface of the fine particles and effectively improving performance of particles.
