▎ 摘  要

NOVELTY - Method for preparing graphene oxide material by adjusting pressure controllable electrolysis, involves using graphite raw material limited and extruded by the mesh container space as a reaction positive electrode adjusting the pressure of the raw material and the voltage between the positive electrode negative electrode, the sequentially reaction and oxidation reaction occurs; stripping and cleaning the material positive electrode the oxidation reaction to obtain the graphene oxide materials. The mesh container is formed by overlapping one or more layers of the mesh materials. USE - Method for preparing oxidized graphene by adjusting pressure controllable electrolysis. Uses include but are not limited to transparent conductive film, printing electron, electrochemical capacitor, lithium battery and polymer composite material. ADVANTAGE - The method ensures that the graphite raw material can continuously participate in the effective electrolytic reaction, through intercalation and oxidation two-step electrochemical reaction to obtain the fully oxidized graphene oxide material. The method reduces the consumption of the electrolyte, realizing high quality of graphene oxide, low cost preparation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the method for preparing oxidized graphene by adjusting pressure controllable electrolysis.
