▎ 摘　　要

NOVELTY - Preparation of graphene/carbon nanotube disperse system macromolecule-based composite material comprises placing carbon nanotube and graphene powder in a liquid medium; crushing the carbon nanotube agglomerate, graphene agglomeration body into single carbon nanotube, single-layer graphene or graphene agglomeration body, or carbon nanotube aggregate of small scale to form a stable graphene/carbon nanotube disperse system; and adding macromolecule material to the graphite/carbon nanotube disperse system as a dispersed phase, and uniformly mixing. USE - Method for the p Preparation of graphene/carbon nanotube disperse system macromolecule-based composite material (claimed) used in aerospace, aviation, electron, automobile, and engineering fields. ADVANTAGE - The composite material has high conductivity, high thermal conductivity, and improved mechanical property.
