The solubility of polyanilines (PANI) was enhanced by introducing polymeric ionic liquid (PIL) into the polymerization synthesis process. The PANIs doped with PILs were found to be soluble in various organic solvents and maintained their chemical structure and conductivity.
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 H-1 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.
