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.
