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。
Using aniline and o-methoxyaniline as monomers, methanesulfonic acid as a doping acid, a solid-phase synthesis of methane sulfonic acid doped aniline and o-methoxyaniline copolymer. The copolymers were characterized by FTIR, UV-Vis absorption, X-ray diffraction, transmission electron microscopy, cyclic voltammetry and conductivity. The results showed that the copolymers with different mole ratios of aniline and o-methoxyaniline were in the intermediate oxidation state. With the increase of the content of o-anisidine, the doping rate of the copolymer decreased. The copolymer has high crystallinity and fibrous morphology. When the mole ratio of aniline to o-methoxyaniline is 1: 1, the copolymer has high electrochemical activity and conductivity of 1.65 S / cm.
