▎ 摘  要

NOVELTY - Preparation of graphene/graphite powder composite material comprises mixing oxidized graphene aqueous dispersion and graphite powder through high-speed stirring, ultrasonically dispersing, spray-drying, pre-expanding, and high-temperature calcining. USE - Method for preparation of graphene/graphite powder composite material used as heat conductive filler (all claimed). ADVANTAGE - The composite material has high thermal conductivity than some common alloy, and reduced interface thermal resistance.
