▎ 摘　　要

NOVELTY - Green preparation of graphene comprises dry grinding a grinding body, a auxiliary grinding medium and graphite to obtain a powder, washing, and drying the powder to obtain graphene. The auxiliary grinding medium is an organic small molecule and has molecular weight of 100-5000. The grinding body is a sphere with a diameter of 1-20 mm. USE - The method is used for green preparing graphene. ADVANTAGE - The method has high yield and peeling efficiency. The prepared graphene has uniform transverse size and less thickness layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene.
