摘　　要：研究了两种聚二茂铁硅烷膜在 6种有机溶剂中的循环伏安 (CV)行为 ,讨论了溶剂性质对膜的CV行为的影响 .在“好”的溶剂中 ,电解质完全解离 ,聚合物膜有适当的溶胀度 ,膜的CV行为表现为可逆的特征 .研究了 3种不同离子体积的支持电解质对聚二茂铁硅烷膜的CV行为的影响 .电解质阴离子参与膜的CV过程 ,其体积大小对膜的CV行为有显著影响 .大阴离子较难渗透进出膜 ,膜内迁移阻力大 ,使膜的CV行为表现为不可逆特征 .The electrochemical behavior of poly(ferrocenylsilane) films in six kinds of organic solvents was investigated with cyclic voltammetry (CV), and the influence of solvent on the electrochemical behavior of the films was discussed. In “good' solvents, the electrolytes were dissociated almost completely, the films were solvent_swollen moderately, and the CV behavior of the films exhibited reversible features. The influences of supporting electrolyte ion volume on the CV behavior of the PFDMS films in organic solvents were investigated too. Electrolyte anions, as counter ions, took part in charges neutralizing in the films, so that the size of the anion affected the CV behavior of the films remarkably.
