Polyaniline （PAn） film was synthesized onto electrode surface modified with a self-assembled monolayer （SAM） of Glutathione （GSH）, while copper was deposited in defects of PAn film simultaneously. The resulted PAn films were characterized by means of cyclic voltammetry and electrochemical quartz crystal microbalance （EQCM）. The results show that there could be the copper ions’ route in PAn films, which make easier adulteration of copper ion into the PAn film phase. It was found that the redox peaks of PAn were relevant to the doping of anions and to the adulteration of copper ion. 聚苯胺 铜离子 修饰电极 电化学石英微天平 分子印迹技术 polyaniline copper ion modified electrode EQCM MIT O657.1 2003-06-01 2021-04-01 6
