摘要：

Protonation of polyaniline base with lightly sulfonated polystyrene in polar solvents such as dimethyl sulfoxide and N-methyl-2-pyrrolidone was investigated by UV-Vis absorption spectra. As the molar ratio of sulfonated polystyrene/polyaniline increases, the conversion from polyaniline base form to salt form is observed owing to increased protonation. The isosbestic point clearly shows that quinoid unit and semiquinoid unit are in equilibrium. They are functions of the sulfonic acid concentration and solvent media.
