Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Specifically, turn on the magnetic stirrer, first set the temperature to an appropriate range, pour 50ml of distilled water and 0.2g of sodium alginate powder measured by an analytical balance into a beaker under a water bath environment. Then place it on a magnetic stirrer and heat and stir continuously. After it is completely dissolved, slowly add graphene oxide powder doped with manganese dioxide into the above solution, continue heating and stirring, and add glycerol to lubricate it after it dissolves. . Place the fully dissolved mixed solution in an ultrasonic cleaner for ultrasonic treatment. Remove excess air bubbles, then cast the treated solution onto a glass mold, and place it in a vacuum drying oven for heat treatment. Finally, the non-metallic electrode film is obtained:

Abstract

The invention provides a preparation process method of a manganese dioxide-doped graphene oxide electrode membrane, and the method comprises the following steps: starting a magnetic stirrer, setting the temperature to a proper range, pouring sodium alginate into a beaker containing 50ml of distilled water, and putting the beaker in a water bath environment; placing the beaker on a magnetic stirrer for continuous stirring, after the mixture is completely dissolved, slowly adding the graphene oxide powder doped with manganese dioxide, continuously performing heating and stirring, and after the mixture is dissolved, adding glycerol to play a lubricating role; placing the fully dissolved mixed solution in an ultrasonic cleaning machine for ultrasonic treatment; removing redundant bubbles, then uniformly casting the treated solution onto a glass mold through a glass rod, and putting the glass mold into a vacuum drying oven for heating treatment to obtain the non-metal electrode film. The manganese dioxide is doped in the graphene oxide through a liquid phase chemical precipitation method to form the composite material, so that the agglomeration phenomenon of the graphene oxide is well improved, and meanwhile, the conductivity and the capacitive performance are improved.

Description

technical field [0001] The invention relates to a preparation process method of a graphene oxide electrode film, in particular to a preparation process method of a manganese dioxide-doped graphene oxide electrode film. Background technique [0002] In recent years, with the upgrading of technology, artificial muscles have come into view. Its characteristics such as small driving voltage, fast response speed and simple structure have aroused people's great interest. The prepared artificial muscle does not need the support of mechanical equipment, and directly converts electrical energy or chemical energy into kinetic energy, and then forms the energy of work done by mechanical devices, requiring less mechanical energy consumption and high conversion rate. Compared with the traditional mechanical transmission, the noise, high cost, and high operation requirements can be completely avoided, and it has excellent characteristics such as low driving voltage, large deflection disp...
