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 .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.
