Studies on chemically synthesized doped poly(o-anisidine) and copolyianiline-{o-anisidine}

Substituted polyaniline poly (o-anisidine) and copolylaniline-(o-anisidine)l were synthesized by the oxidative chemical polymerization method. Sulfuric acid was used as the dopant during the polymerization process. Synthesized polymers were subjected to the spectroscopic, X-ray and thermal analysis. Formation of different oxidation states of the polymer were confirmed by the spectroscopic (UV-VTS and FTIR) analysis. Polymers reveal polycrystalline nature and orthorhombic crystal structure. Three step decomposition patterns similar to that of polyaniline are observed in the thermogram. The conductivity is found to be higher in copoly{aniline-(o-anisidine)} than poly (o-anisidine). Increase in conductivity with increasing temperature was observed in both of the polymers.
