▎ 摘　　要

NOVELTY - Preparing graphene composite material comprises (i) mixing graphene oxide and graphene and stirring to obtain mixture; (ii) adding aggregate and solvent to obtain mixture, mixing and stirring to obtain graphene composite slurry; and (iii) injecting the graphene composite slurry into a mold to carry out a staged heating reaction. USE - The method is useful for preparing graphene composite material with thermal conductivity. ADVANTAGE - The material can be dissolved in the solvent to be used as the radiating paste or heat-conducting adhesive agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene composite material with thermal conductivity prepared by the above method.
