▎ 摘　　要

NOVELTY - Preparing graphene, comprises mixing the graphene oxide solution with a reducing agent and reacting to obtain a reduced graphene oxide solution, adding the dispersing agent into the reduced graphene oxide solution and reacting after mixing to obtain a uniformly dispersed graphene solution, where dispersing agent refers to the ability to react with the reduced graphene oxide solution, and the reaction product is adsorbed on the surface of graphene to avoid the agglomeration of graphene, so that the graphene is uniformly dispersed in the solution. USE - Preparation method of graphene. ADVANTAGE - The graphene has high purity, good dispersion uniformity, good stability, high repeatability, and possibility of application and popularization.
