Spectral and electrochemical studies on blends of polyaniline and cellulose esters

Blends of chemically prepared polyaniline emeraldine base (PANi) with cellulose esters were studied as films by UV-visible spectroscopy and cyclic voltammetry. The cellulose esters used were acetate, propionate, acetate butyrate, and acetate hydrogen phthalate. Films were prepared by casting from N-methylpyrrolidone or formic acid, and the effect of doping by acids on their spectral and electrochemical properti...
