New Strategy and Easy Fabrication of Solid-State Supercapacitor Based on Polypyrrole and Nitrile Rubber
Solid state redox supercapacitors were fabricated using a solid polymer electrolyte, nitrile butadiene rubber (NBR)-KCl and chemically deposited polypyrrole (PPy) as the conducting polymer electrodes on both surfaces of a NBR film. The optimal conditions for the preparation of the PPy/NBR electrode were confirmed as functions of the uptake of pyrrole monomer into the NBR matrix as well as the immersion time in an oxidant solution. The morphology of the PPy-NBR-KCl capacitor was observed using scanning electron microscopy. The performance of the capacitors was characterized using a galvanostatic charge–discharge technique.
