摘要： 采用三种不同氧化剂（FeCl3，(NH4)2S2O8以及由K2S2O8，CuSO4和NaHSO3构成的复合氧化剂），通过界面聚合法合成了聚邻甲苯胺.利用红外光谱、紫外可见光谱、粘度测定、扫描电镜和循环伏安等测定方法，对聚合物进行了表征，并对聚合物形貌、结构及性能进行了初步探讨.结果表明，界面聚合法合成的聚邻甲苯胺呈现出微米级颗粒状分布，颗粒直径大多在几百纳米范围内.所得聚合物表现出较好的电化学活性.采用FeCl3为氧化剂时，聚合物分子链的共轭程度、分子量以及电化学活性最佳.

Abstract:

Poly(otoluidine) was synthesized by interfacial polymerization using iron chloride, ammonium persulfate, and a complex (composed by K2S2O8, CuSO4 and NaHSO3) as oxidant, respectively. The molecular structures,morphologies and electrochemical behaviors were detected by FTIR, UVVIS, SEM and Cyclic voltammetry. The results showed that poly(otoluidine) particles appeared as micro powder and their diameters were within several hundred nanometers. All the three polymers showed good electrochemical activity. When using FeCl3 as oxidant, the molecular weight and conjugated degree, as well as the electrochemical activity of the poly(otoluidine), were the best.
