Abstract

The electrochemical behavior of poly(ferrocenyldimethylsilane-b-dimethylsiloxane) (PFDMS-b-PDMS) films deposited on a glassy carbon electrode was investigated by means of cyclic voltammetry (CV). The influences of the solvent, film thickness, temperature, and PDMS block length in PFDMS-b-PDMS on the electrode process were discussed. It was found that in 0.1 M aqueous LiClO(4) the electrochemical processes of the films on a glassy carbon electrode were complex and have a low rate of electron transport and mass diffusion. The kinetic parameters obtained indicated that the electrode process was controlled by both the electrode reaction and mass diffusion.

摘要

通过循环伏安法（CV）研究了沉积在玻碳电极上的聚（二茂铁基二甲基硅烷 -b -二甲基硅氧烷）（PFDMS -b -PDMS）薄膜的电化学行为。讨论了溶剂、膜厚度、温度以及PFDMS -b -PDMS中PDMS嵌段长度对电极过程的影响。发现在0.1 M 高氯酸锂水溶液中，玻碳电极上薄膜的电化学过程复杂，电子传输和质量扩散速率较低。获得的动力学参数表明电极过程受电极反应和质量扩散共同控制。
