▎ 摘　　要

NOVELTY - Modification of graphene involves heating graphene and amine compound solution in amount of 50-100 pts. wt. with respect to graphene in presence of acid or base catalyst under stirring, and adding obtained graphene to halogenated hydrocarbon. USE - Modification of graphene used for nano-composite material (claimed). ADVANTAGE - The method provides modified graphene having favorable hydrophilicity, electric conductivity, thermal conductivity and mechanical property. The highly-efficient nano-composite material having favorable dispersibility with respect to water is manufactured using the hydrophilic graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nano-composite material, which contains 0.1-10 pts. wt. modified graphene and 100 pts. wt. polymer.
