| 摘 要： | 以谷胱甘肽(GSH)自组装膜电极为基体制备GSH-Cu^2 ／PAn膜，利用分子印迹技术在电化学聚合过程中将铜沉积到聚苯胺的孔穴中。并用循环伏安法和电化学石英微天平监测电极的响应。实验结果表明制得的电极修饰膜内存在Cu^2 的离子通道，使得铜离子的掺杂易于进行；聚苯胺氧化还原峰与阴离子的掺杂及铜离子的掺杂有关。

| Abstract: | 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. |
