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 c

A composite of polyaniline-carboxymethylcellulose has been prepared and it has been found by electronic spectroscopy that polyaniline in the composite exists in the conducting state even when the material is equilibrated with neutral aqueous medium.
