Abstract

A study on the electrochemical oxidation of piperazine and its electrochemical copolymerization with aniline in acidic medium is presented. It was found that the homopolymerization of piperazine cannot be achieved under electrochemical conditions. A combination of electrochemistry, in situ Fourier transform infrared (FTIR), and ex situ X-ray photoelectron spectroscopy (XPS) spectroscopies was used to characterize both the chemical structure and the redox behavior of an electrochemically synthesized piperazine⁻aniline copolymer. The electrochemical sensing properties of the deposited material were also tested against ascorbic acid and dopamine as redox probes.

摘要

本文介绍了在酸性介质中哌嗪的电化学氧化及其与苯胺的电化学共聚反应的研究。研究发现，在电化学条件下无法实现哌嗪的均聚反应。采用电化学、原位傅里叶变换红外光谱（FTIR）和非原位X射线光电子能谱（XPS）相结合的方法，对电化学合成的哌嗪-苯胺共聚物的化学结构和氧化还原行为进行了表征。还以抗坏血酸和多巴胺作为氧化还原探针，测试了沉积材料的电化学传感性能。
