The edge-grafting-modified graphene includes graphene and a water-soluble high-molecular polymer grafted on the edge of the graphene. On the basis of the total mass of the edge-grafting-modified graphene, the mass content of the water-soluble high-molecular polymer grafted in the edge-grafting-modified graphene is 1-30%.
