固相法合成苯胺与邻甲氧基苯胺共聚物及其性能

以苯胺和邻甲氧基苯胺为单体，甲磺酸为掺杂酸，用固相法合成了甲磺酸掺杂苯胺与邻甲氧基苯胺共聚物。 通过红外光谱、紫外可见吸收光谱、X射线衍射、透射电子显微镜、循环伏安和电导率等对共聚物进行了结构表征和性能测试。 结果表明，不同摩尔比的苯胺与邻甲氧基苯胺共聚物处于中间氧化态，随邻甲氧基苯胺含量的增大，共聚物的掺杂率降低。 共聚物具有较高的结晶性和纤维状形貌，当苯胺与邻甲氧基苯胺摩尔比为1∶1时，具有较高的电化学活性,其导电率为1.65 S/cm。

Solid-state Synthesis and Properties of Copolymers of Aniline and o-Methoxyaniline

Copolymers of aniline and o-methoxyaniline were synthesized by solid-state polymerization method using methanesulphonic acid as the doping acid. The resultant copolymers were characterized by FTIR, UV-Vis, TEM, X-ray diffraction, cyclic voltammetry and conductivity measurements. The results showed that the copolymers prepared under different aniline and o-methoxyaniline molar ratios displayed an emeraldine salt phase, and the doping degree of copolymers decreased with increasing content of o-methoxyaniline in monomers. The as-prepared copolymers had a high crystallinity and displayed a fibrillar morphology. The copolymer prepared under the molar ratio of 1∶1, exhibited a higher electrochemical activity than the others, and its conductivity was 1.65 S/cm.
