Fig. 4. Cyclic voltammograms of (a) conventional PANI and (b) LPANI after applying +1.0 V potential for a variable amount of time (0–60 min). (c) Plot of the current intensities in (a) and (b) vs. the time of holding at +1.0 V. The experiment was performed on working electrodes (conventional PANI or LPANI solid deposited on carbon fabric cloth) in acetonitrile with 0.5 mol L⁻¹ sulfuric acid. A Pt wire was used as the counter electrode and Ag/AgCl was used as the reference electrode.
