【Abstract】 The oxidation reaction mechanism of DMcT/PAn with copper ion was investigated by CV curves,Raman spectroscopy,and infrared spectroscopy.The results indicated that the doping of CuC2O4 could improve the homogeneity of DMcT/PAn,increase the conductivity of DMcT/PAn,accelerate the catalysis of PAn on the redox reaction of DMcT,and raise the useful ratio of DMcT/PAn cathode.The doping of CuC2O4 could decrease the solubility of DMcT and its coordination complex in an electrolyte and stabilize the redox processes of DMcT.The doping of CuC2O4 could remove more of the solvent during drying of the cathode films so as to increase the overall specific capacity of DMcT/PAn.更多还原
