▎ 摘　　要

NOVELTY - A modified graphene comprises rutin-modified graphene. USE - Modified graphene. ADVANTAGE - The modified graphene has good dispersibility and low impurity content. The method does not promote graphene chemical damage, maintains integrity of graphene, does not produce waste water and pollutants, and has simple and controllable process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene comprising treating graphene surface with plasma; adding aqueous rutin, dispersing, and standing; and filtering and vacuum drying.
