摘要: Abstract Polypyrrole-based electrodes were fabricated for energy storage applications using cellulose as a substrate material. Films of polypyrrole (pPy) first coated on the via chemical polymerization FeCl 3 an oxidant. To further enhance charge capacity, resulting polypyrrole–cellulose composites (pPy/Cel) with doped anthraquinone-2,6-disulfonic acid (pPy[AQS]) electropolymerization. The capacity was dependent amount electropolymerized polypyrole, which could be controlled by electropolymerization time. cyclic voltammograms revealed that capacities per geometric area (C/cm 2 ) significantly increased and gravimetric from 125 C/g to 250 C/g after These increases attributed redox activities pPy dopant.
