Synthesis and electrochemical stability of polyaniline and polypyrrole in an ambient temperature acetamide—urea—ammonium nitrate eutectic melt

Semiconducting electroactive films of polyaniline and polypyrrole are prepared electrochemically in a room-temperature ternary melt of acetamide—urea—ammonium nitrate. The effect of solvent on the stability, structural and redox properties of the films has been studied. The spectral data indicate that the polymers have structures similar to those prepared in aqueous solutions. The film activity is lower for polyaniline and higher for polypyrrole in the melt when compared to the results obtained in aqueous solutions for the same dopant.
