▎ 摘　　要

NOVELTY - Preparing three-dimensional network structure graphene/nylon nano masterbatch comprises synthesizing nylon raw materials using grained graphene to reduce the formation of graphene three-dimensional network structure, filling with graphene three-dimensional network structure of nylon raw materials in the higher temperature polymerization, carrying out polymerization and granulating to obtain three-dimensional network structure graphene/nylon nano master-batch, where the mass fraction of graphene in the master-batch is 0.2-5% and nylon mass fraction is 95-99.8%. USE - The method is useful for preparing three-dimensional network structure nano master-batch (claimed). ADVANTAGE - The master-batch has high-strength, high thermal conductivity and excellent mechanical property and is economical.
