NOVELTY - The method for preparing modified graphene by two-step process, involves adding graphite and grinding ball to ball mill, adding modifier, ball milling, adding solvent and mixing, when the internal temperature of the ball mill is reduced to room temperature, starting the ball mill to start the reaction, stopping the ball mill after the reaction, collecting the mixed slurry of the grinding ball and graphene, screening and cleaning to obtain modified graphene. USE - Method for preparing modified graphene by two-step process. ADVANTAGE - The method enables simple preparation of modified graphene with high productivity and high quality.
