▎ 摘　　要

NOVELTY - Preparation of modified graphene involves preparing graphene directly by physical method, and modifying prepared graphene by Friedel Crafts alkylation. USE - Preparation of modified graphene (claimed). ADVANTAGE - The process produces modified graphene having improved interface compatibility of graphene and polymer, improved conductivity, and reduced laminated structure. The process is simple, economical, environmentally-friendly, carried out with high efficiency, and suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for modified graphene having a conductivity of 25000 S/m or more.
