Enhancement Cathode Electrode of PPy by GO to Applied for Supercapacitor

Abstract

In this study, chemical oxidation was used to prepare polypyrrole (PPy) composites. Additionally, PPy has been treated with graphene oxide (GO) nanosheets that were produced and added in a certain ratio. The structural characteristics of the mixed polypyrrole and polypyrrole-graphene oxide were investigated. The nanocomposites were produced by adding GO to PPy in volume ratios of 10, 30, and 50%. The molecular structures of PPy, GO, and PPy-GO nanocomposites were determined. The formation of a network of polypyrrol nanofibers was confirmed. Nanocomposites were produced by doping PPy nanofibers with GO in various amounts (10%, 30%, and 50% volume ratios). According to the electrochemical experiments, the nanocomposites exhibit high pseudocapacitive activity.
