| Summary: | 碩士 === 大同大學 === 材料工程學系(所) === 101 === This research mainly manganese oxide / graphene oxide as a composite material, the use of graphene oxide with high specific surface area in order to enhance the reaction of manganese oxide. Scan using SEM EDS mapping graphene oxide of manganese in the distribution of the surface, namely that the addition of potassium permanganate different weight ratio will be 125% coverage is wide. The XRD and EPR, respectively, adding that the high proportion of potassium permanganate is obtained when a larger proportion of manganese (IV) and capacitance value is higher.
Add different weight ratios of carbon black with different weight ratios of potassium permanganate prepared electrode potentiostat (Jiehan 500 electrochemical workstation) for cyclic voltammetry tests find its capacitance value. The results showed that the addition of different weight ratio of 40% to 100% of carbon black and potassium permanganate test strip has a higher capacitance value 58.809 F / G.
