Abstract

The effects of $ZnCl_2$ on the electronic properties of polyaniline-HCl salt and its base were studied for different concentrations of $ZnCl_2$ ( 0.1, 1.0, 3.0 and 6.0 M) for 1 and 5 days. The polyaniline samples were characterized by conductivity and spectroscopic measurements such as UV-Vis, FT-IR and EPR. $ZnCl_2$ treatment results in the degradation of the polyaniline salt and, for the polyaniline base, doping occurs depending on the concentration of $ZnCl_2$. The conversion of polyaniline base to polyaniline salt is less efficient in the case of $ZnCl_2$ doping when compared to doping with HCl. There is no significant change in the properties of polyaniline salt and base with increase in duration of $ZnCl_2$ treatment. The poor charge storage capacity and shelf-life of the polyaniline-zinc cell system can be understood from the present study.
