To enhance the solubility of polyanilines (PANI), polymeric ionic liquid (PIL) was introduced into the polymerization synthesis of PANI with various proportions. The structure and properties of the modified PANIs were characterized by ¹H NMR, Fourier transform infrared spectroscopy, thermogravimetric analysis, ultraviolet-visible spectrum, etc. It was found that the obtained PANIs doped with PILs were soluble in various organic solvents such as N,N-dimethyl formamide and acetonitrile. Compared with the pure PANI, the PANIs doped by PILs showed remarkable solubility and their chemical structure and conductivity kept integrated.

聚合物离子液体辅助聚合制备可溶性聚苯胺纳米纤维

为了提高聚苯胺（PANI）的溶解度，将聚合物离子液体（PIL）以各种比例引入到PANI的聚合合成中。通过¹ H NMR，傅立叶变换红外光谱，热重分析，紫外可见光谱等对改性PANI的结构和性质进行了表征。发现所获得的掺杂PIL的PANI可溶于各种有机溶剂，如N，N-二甲基甲酰胺和乙腈。与纯PANI相比，PIL掺杂的PANI表现出显着的溶解性，并且其化学结构和电导率保持集成。
