제목 Hybrid Multilayer Flexible Thin Film Supercapacitor of Graphene Nanosheets with Polyaniline: Importance of Establishing Intimate Electronic Contact through Nanoscale Blending
초록 Hybrid electrode consisting of electric double-layer capacitor of graphene nanosheets and a pseudocapacitor of conducting polymer polyaniline exhibits a synergistic effect with excellent electrochemical performance for flexible thin film supercapacitor. This hybrid supercapacitor is constructed by a nanoscale blending method of layer-by-layer (LbL) assembly based on the electrostatic interactions between positively charged polyaniline (PANi) and negatively charged graphene oxide (GO) nanosheets. The hybrid electrode provides not only improved the electronic conductivity and flexibility through the intimate contact with graphene nanosheet, but also enhanced chemical stability during charge-discharge process. This study opens up the possibility of production of diverse graphene-based hybrid nanocomposites that are promising for future flexible supercapacitors.
