| titleOfInvention | Self-supporting graphene manganese dioxide nanowire composite film electrode and preparation method thereof |
| abstract | The invention discloses a self-supporting graphene manganese dioxide nanowire composite film electrode and a preparation method thereof. The preparation method comprises the following steps: applying a first voltage between a working electrode and a counter electrode to expand the graphite foil, applying a second voltage to peel off the graphene to obtain a graphene sheet, then washing and ultrasonically cleaning for multiple times, and finally drying to obtain electrochemical peeled graphene; dissolving potassium permanganate and potassium persulfate to obtain a mixed solution, performing hydrothermal reaction, and finally cleaning and drying a product to obtain a manganese dioxide nanowire; dispersing electrochemical stripping graphene in a solvent to obtain a graphene solution, dispersing manganese dioxide nanowires in the graphene solution to obtain a mixed solution, performing suction filtration to remove the solvent to obtain a composite membrane, and finally drying the composite membrane to obtain the composite membrane. The method has the advantages of simple process and high yield, and the composite film electrode has high mass specific capacitance, good area specific capacitance and excellent cycling stability, and has a good application prospect. |
