▎ 摘　　要

NOVELTY - A graphene-treating agent comprises 1000 pts. wt. organic solvent, 50-240 pts. wt. chlorine/bromine-containing organic acid and 30-150 pts. wt. chloro/bromo-thiophene or its derivatives. USE - Agent is used for treating graphene in manufacture of graphene-reinforced composite material (all claimed). ADVANTAGE - The graphene-treating agent has excellent structural stability and reliability, and high strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene-reinforced composite material, which involves mixing 50-180 pts. wt. graphene and graphene-treating agent, evaporating the organic solvent to obtain a mixture of graphene and remaining organic ingredients, mixing with plastic and performing injection molding to obtain molded metal/alloy base material; and (2) graphene-reinforced composite material.
