▎ 摘　　要

NOVELTY - Modifying graphene comprises (i) dissolving graphene in water to obtain graphene solution, adding a dispersant and then mixing to obtain graphene dispersion, (ii) adding acrylamide monomer and cross-linking agent to graphene dispersion, mixing and stirring, and pre-cooling to obtain pre-cooling solution, (iii) adding initiator and accelerator to pre-cooling solution, mixing and stirring and then transferring the mixture to mold for sealing, and (iv) cooling mold, then thawing, taking out gel for cleaning and drying to obtain modified graphene composite material. USE - The method is useful for modifying graphene. ADVANTAGE - The method: improves dispersity of graphene, prevents its agglomeration and nanoparticles loss and enhances reusability.
