用循环伏安法研究烷氧基聚紫精的电氧化还原性能

Study on Electroredox Behaviors of Alkoxyl Viologen Polymers with Cyclic Voltammetry

摘要: 利用循环伏安法研究了烷氧基聚紫精的电氧化还原性能，测定了它们的两步还原电位、峰电流和表现扩散系统（Ｄ），结果表明：Ｄ随着ＰＡｏＶ结构中所含醚键的增加而减小；并对第一步还原反应的可逆性进行了研究，发现第一步还原反应的可逆性优于第二步还原反应，同时证明电极反应是由扩散步骤控制的；ＰＡｏＶ具有良好的抗电疲劳性能；并研究了体系ｐＨ值和扫描范围对ＰＡｏＶ的电氧化还原性能的影响。

Abstract: The electroredox behavior of alkoxyl viologen polymers(PAoV) was studied with cyclic voltammetry. The two step redox potentials and diffusion coefficients were determined, and the reversibility of the first step electrore-duction was also studied. The res
