摘要
采用电化学交流阻抗技术对一种新型电极表面修饰的自组装多层膜进行表征 ,通过阻抗谱分析 ,得出电荷传递电阻和双电层电容与膜层数的关系。证明该多层膜随层数增加具有均匀增长。
A new multilayer film fabricated based on electrostatic attraction in this laboratory was firstly characterized by the electrochemical impedance spectroscopy. The relationship between the charge-transfer resistance and double-layer capacitance with the number of layers was obtained through analyzing the impedance data. It demonstrated that the multilayer film showed a unique structure with the film growth. Compared to other electrochemical methods, the electrochemical impedance spectroscopy was proved to be a very sensitive and useful technique for characterizing the multilayer films.
