| 摘 要： | 采用紫外-可见吸收光谱法现场监测了苯胺电化学聚合时的动力学降解过程，简单、直观地显示了阳极电位、酸度和苯胺浓度对降解过程的影响，结果表明，阳极电位越正、酸度越强、苯胺浓度越大，聚苯胺的降解速度越快。该方法得到的结果与聚苯胺膜在空白溶液中采用循环伏安法研究其降解动力学时得到的结果类似。

| Abstract: | Kinetic degradation process of PAn films during aniline polymerization was in situ monitored by UV-Visible absorption spectrum. The effects of anodic potential, acidity and monomer concentration on the degradation process were also investigated. The experiment results displayed that the more positive the anodic potential, the higher the acidity of the solution, the higher the concentration of aniline, the faster the PAn films degradation speed. Which was similar to the results obtained when the kinetic degradation process of PAn films was studied in blank solutions by cyclic voltammetry. |
