摘要　应用循环伏安法研究经HCl、TSA和HClO4等不同酸掺杂的聚间甲氧基苯胺(PmMAn)的电化学活性.结果表明,HClO4是合成PmMAn的最佳酸介质,在此介质中得到的聚合产物具有良好的氧化还原活性.FT IR,SEM和XRD测试分别说明,酸根离子作为抗衡阴离子嵌入PmMAn分子链,并对聚合物的氧化还原活性有较大影响;PmMAn表现出典型的高分子晶体性质,符合单斜晶系的特征. Poly(m-methoxyaniline), PmMAn, was prepared in the presence of HCl, p-toluene-sulfonic acid and perchloric acid. By using cyclic voltammetry, the effect of different acid dopant on electrochemical activities of PmMAn was studied. The results showed that perchloric acid is the best acid to prepare PmMAn with good electrochemical activities The FTIR spectra indicate that the acid radical anions have embedded into PmMAn molecularchain as counter-ion during synthetic process, and this great influences the redox activities of PmMAn. SEM and XRD measurements illustrate that PmMAn is characterized by its typical molecular crystalline being monoclinic.
