▎ 摘  要

NOVELTY - High-thermal-conductivity and insulating polymer material composition comprises 60-90 wt.% polyvinylidene fluoride and 10-40 wt.% hybrid fillers, where the hybrid fillers are ceramic thermal-conductive filler-graphene hybrids. The weight ratio of graphene to ceramic thermal-conductive fillers is 1:(2-200). USE - Used as a high-thermal-conductivity and insulating polymer material composition. ADVANTAGE - The polymer material composition has higher thermal conductivity and insulativity under low filler content. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing polymer material composition, comprising: (i) mixing graphene oxide with amino-group functionalized ceramic thermal conductive filler nanomaterial in a solvent via electrostatic self-assemble to obtain a condensate, adding polyvinylidene fluoride into condensate, mixing uniformly to dissolve completely, precipitating out and filtering the membrane; and (ii) using reducing agent to reduce the graphene oxide in the membrane composition at 70-90 degrees C, washing and drying.
