The Electrochemical Behavior of EDOT and PEDOT

Figure 14.1 demonstrates the irreversible oxidation of EDOT at 1.39 V versus Ag/AgCl (c = 1.7 × 10-2 M in propylene carbonate + 0.1 M TBAPF6 (tetran-butylammonium hexauoro-phosphate); 20°C, sweep rate ν = 100 mVs-1).3 In Figure 14.2, multisweep voltammograms are drawn, obtained under the same experimental conditions. Current increase with each cycle is observed, resulting in the formation of PEDOT:PF6 lms on the platinum electrode.
