▎ 摘　　要

NOVELTY - A graphene/epoxy resin composite material based on lamellar anisotropy is obtained by controllable compression of graphene aerogel, then mixing with epoxy resin and curing. The composite material has a shell-shaped brick mud structure. USE - Graphene/epoxy resin composite material. ADVANTAGE - The composite material has high thermal conductivity and toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene/epoxy resin composite material, which involves: (i) preparing the lamellar anisotropic graphene aerogel by subjecting a mixed solution of graphene oxide and polyamic acid salt to bidirectional freezing, imidization and graphitization; and (ii) carrying out controllable compression on the graphene aerogel, then mixing with epoxy resin, and curing.
