▎ 摘 要
NOVELTY - Preparing graphene-boron composite material involves repeatedly melting and cooling nano graphene powder, nano boron nitride and polyvinyl chloride, where melting and cooling is performed for 3-5 cycles. USE - Method for preparing graphene-boron composite material used for preparing electronic packaging material (claimed). ADVANTAGE - The method enables to prepare graphene-boron composite material, which has excellent heat conducting property.
