▎ 摘　　要

NOVELTY - Preparing graphene nanosheet composite powder, comprises mixing graphite powder, grinding aid powder and first solvent to obtain a composite powder mixture in a mass ratio of (1-1.5):(2-5):1000, stirring the composite powder mixed liquid at a periodically changing rotational speed, obtaining the graphene nanosheet composite mother liquor, filtering the graphene nanosheet composite mother liquor and drying to obtain the graphene nanosheet composite powder. USE - The method for preparing graphene nanosheet composite powder used for organic resin, composite modification of inorganic gel material, and wide application prospect and value. ADVANTAGE - The method enables to prepare graphene nano-sheet composite powder that has high efficiency, low cost and easy characteristics, and can be directly used for organic resin, composite modification of inorganic gel material, and has wide application prospect and value.
