▎ 摘　　要

NOVELTY - Preparing graphene, comprises mixing graphene oxide solution with a reducing agent and reacting to obtain a reduced graphene oxide solution, adding dispersing reactant into the reduced graphene oxide solution to mix and react to obtain a uniformly dispersed graphene solution containing impurities, where the dispersing reactant refers to being able to react with the reduced graphene oxide solution, and the reaction product uniformly disperses the graphene in the solution, adding the uniformly dispersed graphene solution into the solvent for filtration to obtain the uniformly dispersed graphene solution in the solvent, where the solvent is an inorganic solvent or an organic solvent. USE - The method is useful for preparing graphene. ADVANTAGE - The graphene prepared by the method has high purity, good dispersion uniformity, good stability, high repeatability, and possibility of application and popularization. The graphene can be uniformly dispersed in each kind of solvent, comprising water and various organic solvent and can quickly and completely remove impurities in the graphene production preparation process, reducing the preparation cost of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the steps of the method for preparing graphene (Drawing includes non-English language text).
