▎ 摘　　要

NOVELTY - The preparation method of high thermal conductive graphene nanocomposite material involves (i) physically and chemically combining liquid crystal and graphene to obtain liquid crystal-graphene, and (ii) filling liquid crystal-graphene into polymer matrix material to obtain a liquid crystal-graphene/polymer composite material. USE - Preparation of high thermal conductive graphene nanocomposite material (claimed). ADVANTAGE - The method enables the preparation of high thermal conductive graphene nanocomposite material having excellent liquid crystallinity, anisotropy performance, heat transfer property, and thermal conductivity.
