Infrared spectroscopic study of solid-state protonation and oxidation of polyaniline

Infrared spectrum of the polyaniline sulfate was compared with the spectrum of the polyaniline base after solid-state protonation with an equimolar am ount of camphorsulfonic acid and with the spectrum of the polyaniline base after solid-state oxidation with ammonium peroxodisulfate. In both cases el ectrically conducting product was obtained, The bands characteristic of con ducting protonated or oxidized form were identified in the spectra of the b lends.
