▎ 摘　　要

NOVELTY - Preparation of polymer grafted graphene comprises adding (pts.wt.) graphene or hydrogenated graphene (1), solvent (10-1000), and vinyl monomer (10-1000), adding 0.01-10 pts. wt. initiator while blowing nitrogen, heating to 55-90 degrees C, reacting for 1.5-60 hours, depositing, centrifuging, washing, and drying to obtain product polymer grafted graphene. USE - Preparation of polymer grafted graphene used in mu m or nm-electrons, machinery, chemical industry, or and high performance materials. ADVANTAGE - The method can graft polymers on graphene. The graphene product has good dissolubility, solution working quality, and good electric conductivity.
