| Abstract: | Phosphoric acid doped polyaniline has been
synthesized chemically and electrochemically and tested for its specific
capacitance properties by constructing a supercapacitor using stainless steel
electrodes. Both the samples are characterized by UV-vis, FTIR, XRD and
electrochemical methods. The electrochemically grown samples exhibit higher
capacitance values in the range of 244-305 F/g. This is due to the higher
purity of the electrochemically prepared polymer due to repeated cycling of the
potential. Chemically prepared samples show lower capacitance values due to
over-oxidation of the polymer and presence of impurities. |
