▎ 摘　　要

NOVELTY - Preparing graphene comprises (i) mixing adsorption medium and graphite and then placing in compacting machine, (ii) starting the roller compaction machine, and mixing thoroughly for repeated rolling for few hours to fully contact the mixture of graphite and the adsorbing medium, then peeling off graphite layer and adhered to the absorbing medium surface, and (iii) removing the mixture of the above steps, then dissolving in water, filtering out of solid matter, and then washing solid material with water, then ultrasonically stripping filtering, drying and purifying to obtain final product. USE - The method is useful for preparing graphene (claimed). ADVANTAGE - The graphene: enhances the degree of adsorption.
