采用界面聚合法在樟脑磺酸存在的状态下合成了聚苯胺、聚邻甲氧基苯胺以及苯胺与邻甲氧基苯胺的共聚物。利用红外光谱,紫外可见吸收光谱,电子扫描微电镜,X-射线粉末衍射,循环伏安,电导率测试等手段对聚合物进行了表征,初步探讨了单体配比对共聚物形貌、结构及性能的影响。结果表明,界面聚合法合成的上述各聚合物均呈现微米级颗粒状分布,颗粒直径大多在100nm以内;共聚后聚合物的结晶性能下降;循环伏安及电导率测试结果表明,随着聚合物主链中邻甲氧基苯胺结构单元的增加,聚合物的电化学活性及电导率呈下降趋势。
Polyaniline, poly-o-methoxyaniline and copolymers of aniline and o-methoxyaniline were synthesized by the interfacial polymerization method in the presence of camphor sulfonic acid. The polymer was characterized by IR, UV-Vis, SEM, XRD, cyclic voltammetry and conductivity test. The effects of monomer ratio on the morphology, structure And the impact of performance. The results showed that all of the above polymers synthesized by interfacial polymerization exhibited a granular distribution of micron size with particle diameters mostly within 100 nm. The crystallinity of the polymer decreased after the copolymerization. The cyclic voltammetry and conductivity measurements showed that with the increase of polymer The main chain of o-methoxyaniline structural unit increases, the electrochemical activity of the polymer and the conductivity showed a downward trend.
