摘要： 使用循环伏安法实现了硫堇在酸性溶液中的电化学聚合.聚硫堇是一种蓝色物质，它的颜色能随电位迅速变化.在0.50 mol•dm－3 HCl 至pH 6.0的溶液中，聚硫堇具有很好的电化学可逆性、稳定性和快速传递电子的能力.测定了聚硫堇的可见光谱和红外光谱，根据红外光谱，提出了硫堇的电化学聚合机理的假设.

Abstract: The electrochemical polymerization of thionine in the aqueous acetic solution has been carried out using cyclic voltammetry. Polythionine is a blue material. Its color can be quickly changed by applied potential. Polythionine has a good electrochemical reversibility, stability and a fast charge transfer ability in the solution of 0.50 mol•dm－3 HCl to the solution of acetate of pH 6.0. Visible and FTIR spectra of polythionine have been presented in this paper. Based on FTIR spectra, a suggestion for mechanism of polymerization of thionine is presented.
