本文报道了溶液pH值对聚邻甲本胺电化学性质的影响。研究结果表明,电化学合成的聚邻甲苯胺的循环伏安曲线、氧化电位、膜的颜色、充放电容量、紫外可见光谱以及氧化还原活性都受到溶液pH的影响。在低pH值的溶液中,随着扫描电位的变化,聚邻甲苯胺膜的颜色可逆地变化,而在pH4.13的溶液中进行扫描时,膜的颜色不变化,电化学活性也消失。 This paper reports the effect of solution pH on the electrochemical properties of poly (o-methylamine). The results show that cyclic voltammetry, oxidation potential, membrane color, charge and discharge capacity, UV-Vis spectra and redox activity of poly (o-toluidine) electrochemically synthesized are all affected by the pH of solution. In the low pH solution, the poly-o-toluidine film reversibly changed its color with the change of the scanning potential. However, the color of the film did not change and the electrochemical activity disappeared when the solution was scanned at pH4.13.
