二茂铁基超支化聚氨酯的电化学性能

摘要

The electrochemical property of ferrocene modified hyperbranched polyaminoester (HPAE-Fc) was carried out by cyclic voltammetry, The results showed that HPAE-Fc had a single pair irreversible waves, when ferrocene was grafted to the HPAE, the ferrocenyl groups maintained their redox independence, and had strong electron transfer rate, which were pre-' conditions for properties of electrochemical and catalytic. Based on the analysis of the relationship between peak potential, peak current and scan rate, it was found that the electrochemical process was controlled by both mass diffusion and electrode reaction.%通过循环伏安法(CV)测定了二茂铁基超支化聚氨酯(HAPE-Fc)的电化学性能.结果表明:HPAE-Fc表现为单对氧化还原峰,在二茂铁接枝到超支化聚氨酯上以后,二茂铁基团依然保持着自身的氧化还原独立性,具有较强的电子转移速率,这是其具有电化学特性和催化作用的前提条件.通过分析扫描速率与HPAE-Fc电化学行为之间的关系,发现HPAE-Fc的电极过程既受扩散控制,同时也受电极反应的控制.
