▎ 摘　　要

NOVELTY - Preparation of graphene involves placing crystalline flake graphite, vinyl ester resin, silane coupling agent, hyperdispersant, organic bentonite, fumed silica and N-methyl pyrrolidone in a ball-milling tank, grinding by using stainless steel ball as grinding medium, refining auxiliary dispersant stainless steel ball grinding medium under ultrasonic condition, discharging, filtering and removing stainless steel balls. USE - Preparation of graphene (claimed). ADVANTAGE - The method enables the industrial production of graphene by simple and easy operation at reduced cost.
