NOVELTY - Preparing a functionalized graphene slurry involves adding mixed raw materials to a ball mill and then ball milling to obtain a graphene slurry. The raw materials include graphite, p-substituted aniline, nitrite compound and solvent, where the p-substituted aniline and nitrite compound are not added to the ball milling at the same time. USE - The method is useful for preparing a functionalized graphene slurry, which is useful as an electrode material for a lithium-ion battery or a supercapacitor, and for a coating, an ink and a polymer matrix composite material. ADVANTAGE - The method enables simple preparation of the functionalized graphene slurry with excellent dispersibility.
