▎ 摘　　要

NOVELTY - Preparing graft-graphene fusion-bonded nano-metallograpan-metal composite involves subjecting graphene fused body forming multiple nano-graphene-metal complexes on surface of the nano-graphene, where nano-graphene-metal composite comprises nano-metals for bonding the nano-grapins, forming a polydopamine layer on the outer surface of the nano-graphene-metal composite, and heat-treating the nano-graphene-metal composite to obtain graft-graphene fusion-bonded nano-metallograpan-metal composite which is melt-bonded to nano-graphene-metal composite. USE - Method for preparing graft-graphene fusion-bonded nano-metallograpan-metal composite (claimed). ADVANTAGE - The method enables to prepare graft-graphene fusion-bonded nano-metallograpan-metal composite which has improves peel strength, improves barrier performance of the gas lamp, increases dispersibility, and has minimizes mechanical strength.
