▎ 摘　　要

NOVELTY - Preparing graphene comprises (i) preparing raw material of graphene, fully mixing to obtain the mixed solution, (ii) adding graphite powder in the mixed solution of the step (i), placing the obtained mixed solution directly in the reaction device to mechanical stripping to form a mixed solution of the graphene, (iii) centrifuging peeling off in solution separating obtain the initial graphene, and (iv) placing the material into a drier for drying to obtain the graphene. USE - The method is useful for preparing graphene. ADVANTAGE - The method: avoids material waste, avoids the human factor, ensures the product quality, and realizes mass production of graphene.
