The doping of MnO2 could enhance the electrochemical activity and reversibility of the copolymer. When used as the electrode materials of a supercapacitor, the capacitive behaviors of the as-prepared PANOA-MnO2 were superior to those of pure PANOA, especially at high potential scan rate and high charge-discharge current density. The MnO2 doped copolymer also had an excellent cyclic performance.展开更多
