Polyaniline has been synthesized by the chemical and electrochemical oxidation of aniline. The conductivities increase by seven order of magnitude upon protonation. The IR absorption band near 1590 cm −1 shifts to a lower frequency upon protonation. Visible spectra vary with the degree of protonation and the applied potential. Cyclic voltammetry indicates that polyaniline exists in several forms.
