▎ 摘　　要

NOVELTY - Sulfur-substituted fluorinated graphene/epoxy composite material comprises 0.2-15 wt.% sulfur-substituted fluorinated graphene and 85-99.5 wt.% epoxy resin. USE - The sulfur-substituted oxyfluorinated graphene/epoxy resin composite material is used in the fields of coatings, building and electrical appliances (claimed). ADVANTAGE - The composite has good dispersibility, increased material hardness and enhanced impact resistance. The method has simple and feasible process, convenient operation and strong universality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing sulfur-substituted oxidized fluorinated graphene/epoxy resin composite material, comprising (i) mixing sulfur-substituted fluorinated graphene, organic solvent and epoxy resin to obtain mixed system, (ii) removing the organic solvent in the mixed system obtained in step (i), and (iii) adding curing agent into the reaction system, removing the organic solvent, performing curing reaction to obtain sulfur-substituted fluorinated graphene/epoxy resin composite material.
