NOVELTY - The preparation method of graphene by liquid phase chemical intercalation of graphite involves (1) soaking graphite in a mixed acid solution, adding intercalant, and stirring to obtain a mixed solution, and (2) adding an organic reagent to the mixed solution obtained in the step (1) to obtain aqueous dispersion liquid of graphene. USE - Preparation method of graphene by liquid phase chemical intercalation of graphite (claimed). ADVANTAGE - The method enables preparation of graphene with high yield, graphene oxygen content of 1.63%, reduced oxygen content, and high electrical conductivity.
