▎ 摘　　要

NOVELTY - Preparing graphene dispersion involves using electrochemical auxiliary ultrasonic method, preparing inorganic salt with certain concentration/inorganic acid aqueous solution as electrolyte, taking metal and alloy or non metal conductor material of chemical and non-chemically stable as cathode, graphite rod as anode in electrolyte constant voltage rapidly electrolytic peeling off anode graphite rod in electrolyzing process, controlling solution temperature at 20-30 degrees C, filtering and collecting peeling substance, and then washing and drying to obtain graphite intercalation compound, putting graphite intercalation compound into organic solvent, and performing ultrasonic treatment, centrifuging and collecting supernatant liquid to obtain graphene dispersion liquid. USE - Method for preparing graphene dispersion. ADVANTAGE - The method enables to preparing graphene dispersion which is simple, easy to control, eco-friendly, cost-effective, and it realizes industrial production.
