▎ 摘　　要

NOVELTY - Preparing graphene oxide electrode film doped with manganese dioxide comprises (a) opening magnetic stirrer, (b) setting the temperature to the proper range, (c) pouring sodium alginate into the beaker filled with 50 ml distilled water, (d) placing the beaker in the water bath environment, (e) placing on the magnetic stirrer for continuous stirring, (f) slowly adding the graphene oxide powder doped with manganese dioxide, continuously heating and stirring, (g) dissolving, and adding glycerol to lubricate, (h) placing fully dissolved mixed solution in an ultrasonic cleaning machine for ultrasonic treatment, and removing the redundant bubbles, and (i) uniformly casting the processed solution on the glass mold through the glass rod, placing in the vacuum drying box for heating treatment, and obtaining non-metal electrode film. USE - The graphene oxide electrode film doped with manganese dioxide is used as electrode film of driving device. ADVANTAGE - The graphene oxide electrode film has good electrochemical and mechanical properties, has good energy storage effect, is environmentally friendly, and has no toxicity. The method is simple and eco-friendly, has low cost, uses liquid phase chemical precipitation method to make the graphene oxide doped with manganese dioxide to form composite material, improves agglomeration phenomenon of the graphene oxide, and improves conductivity and capacitance performance. The graphene oxide has super-large surface area, perfect lattice structure and good application prospect.
