NOVELTY - Dispersion of multilayer graphene comprises taking multilayer graphene into acidic oxidizing liquid, mixing, heating, stirring, removing acid, obtaining graphene aqueous slurry, adding solvent, diluting, and obtaining graphene dispersion liquid. USE - Method for dispersing multilayer graphene (claimed). ADVANTAGE - The method avoids high-power ultrasonic or grinding, less energy consumption, low cost, does not need surfactant or dispersing agent, reduces impurities affecting graphene performance, simplifies subsequent material processing, and keeps intrinsic properties of graphene material.
