▎ 摘　　要

NOVELTY - A graphene/polyethylene composite material is prepared by preparing positive charge coated graphene (P-GNPs), preparing negative charge coated polyethylene (N-PE), ultrasonically dispersing P-GNPs and N-PE in absolute ethanol and stirring, uniformly absorbing P-GNPs at outer surface of N-PE particles, vacuum filtering, collecting P-GNPs-N-PE microsphere, placing in mold, hot pressing processing and cold pressing processing. USE - The method is used for preparing graphene/polyethylene composite material. ADVANTAGE - The material has honeycomb graphene frame by simple safety controllable technique and improves thermal conductivity.
