摘要
本文研究了单取代二茂铁酯和双取代亚麻酸二茂铁酯LB膜修饰Pt电极的循环伏安性能,用修饰电极的循环伏安模型对实验结果进行拟合,计算了在转移压力分别为20,30,40mN.m^(-1)下LB膜修饰Pt电极的覆盖度,并分析和讨论了不同转移压力下修饰的二茂铁LB膜的电荷转移中介作用.
The cyclic voltammetric behaviors of Pt electrode modified with ferrocene derivative LB films were studied in K4Fe(CN)6 and ascorbic acid solutions respectively. Cyclic voltammetric theory (model) of modified electrode was employed to obtain the experimental data using a computer fitting approach. Quantitative agreement between experiment and theory was obtained. The coverage of LB films modified on Pt electrode under surface pressure of 20, 30, 40 mNm-1 was estimated and the mediation of charge transfer of modified LB films under different surface pressure was discussed.
