▎ 摘　　要

NOVELTY - Controlling electrical sedimentary graphene film in a Zeta potential comprises (i) scattering graphene in water to prepare a graphene dispersing solution with a concentration of 0.01-3 mg/ml by mechanical stirring, separating the graphene slurry at different speed interval by different speed, scattering the graphene paste in different speed intervals in the water again, where the graphene dispersed liquid with a concentration of 0.01-3 mg/ml is configured, and its pH value is adjusted with alkaline reagent graphene electric solution; and (ii) cleaning and fixing the ultrasound in the electrolyte as an anode, where the current density is 0.1-2 mA/cm2and obtaining graphene film with different slices. USE - The method is useful for controlling electrical sedimentary graphene film in Zeta potential. ADVANTAGE - The method achieves the graphene Zeta potential by the control of the decentralized solution and the control of the pH value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene film by Zeta potential control electrophoretic deposition
