| 摘 要： | 苯胺在碱性溶液中电化学氧化时，阳极上形成深黄色的聚苯胺，其氧化峰电位为０．７Ｖ（ｖｓ．Ａｇ／ＡｇＣｌ含饱和ＫＣｌ溶液），比在酸性溶液中氧化约低０．３Ｖ，环一盘电极实验结果表明，在碱性溶液中，苯胺氧化时生成两种可溶性的中间物，形成的聚合物颜色不随电位和ｐＨ值而变化，在空气和碱性溶液中具有很高的稳定性，在紫外－可见光谱图上，聚合物的吸收峰出现在５００ｍ左右。

| Abstract: | A deep yellow polyaniline was formed at the anodic electrode during electrochemical oxidation of aniline in the alkaline solution.The peak of oxidation potential for aniline in the alkaline solution was 0. 7 V (vs.Ag/AgCl with a saturated KCl solution),which is about 0. 3V less than that in the acidic solution.The results from rotating ring-disk electrode experiment show that two soluble intermediates were generated during electrochemical oxidation of aniline.The colour of the polymer in the alkaline solution is independent of applied potential and pH values.An adsorption peak was observed in the UV region at 500 nm for the polymer.The polymer has a high stability in air and the alkaline solution. |
