ABSTRACT
In this paper, the preparation of electroactive polymers artificial muscle electrode membrane with graphene oxide and manganese dioxide as the main research material to explore the performance of electrode membrane. Using sodium alginate as matrix, manganese dioxide with different mass ratios was compounded with graphene oxide and sodium alginate aqueous solution to prepare electrode films. The effects of manganese dioxide on the morphology and electrochemical properties of electrode films were discussed. From the test results, it can be seen that the scanning electron microscopy results show that the manganese dioxide layer is uniformly compounded on graphene oxide. With the increase of manganese dioxide/graphene oxide mass ratio, the specific capacitance of the electrode film gradually increases and the impedance increases. With the increase of driving voltage, the deflection displacement gradually increases and then shows a downward trend. When the mass ratio of manganese dioxide/graphene oxide is 0.1(# 2), the maximum deflection displacement is 14.1 mm, which is 2.76 times of the minimum deflection displacement of the sample (# 1). The specific capacitance of the electrode film was increased by 1.57 times to 15.62 F · g−1. Finally, the performance difference of graphene oxide electrode film and multi-walled carbon nanotube electrode film on EAP artificial muscle was explored.
