Abstract

UV-visible spectra of polyaniline and its polyelectrolyte complexes show evidence for different degree of protonation when equilibrated with different ionic strength at a particular pH, due to the Donnan effect. For pure polyaniline, when the fixed charge on the film is positive, protonation is higher ionic strength whereas, when the polyaniline is doped with a polyelectrolyte resulting in a net negative fixed charge on the film, the protonation is less at higher ionic strength.
