▎ 摘　　要

NOVELTY - Graphene-polymer composite heat-conductive material comprises 1-10% graphite filler, 100% base polymer, 10-60% curing agent, 1-10% dispersant and 60-90% solvent. USE - The graphene-polymer composite heat conductive material is useful for graphene-polymer composite heat-conductive film (claimed). ADVANTAGE - The graphene-polymer composite heat conductive film has good heat dissipation effect in the field of electronic products. The method makes graphene to form complete heat-conducting network in polymer and significantly improves heat conductivity of polymer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for preparing graphene-polymer composite heat-conductive film, comprising separately dissolving base polymer, dispersing agent and curing agent in solvent and mixing, adding graphene filler dispersed in solvent and curing.
