Abstract
Conductive polyaniline was synthesized in aqueous 1.0 M oxalic acid co ntaining 0.1 M aniline by electrochemical and chemical oxidation and c haracterized by conductivity, solubility, ultraviolet and infrared spe ctroscopy, and cyclic voltammetry. The solubility experiments showed t hat the solubility of oxalic acid-doped polyaniline in dimethylsulfoxi de and dimethylformamide increased to a certain extent. The soluble pa rt of the polyaniline was free from impurities such as quinones. Cycli c voltammetric studies in oxalic acid medium revealed that aniline exh ibited a similar behaviour to that in H2SO4 and the polymerization rat e was much slower than that in H2SO4.
