Characterization of the PEDOT:PDA electrodes electropolymerized in different electrolyte solvents. (A) Representative optical micrographs of 2 mm diameter PEDOT:PDA electrodes coated using different electrolyte solvents. (B) CV scans in [Fe(CN)6]3−/4− at 100 mV s−1 scan rate. (C) Impedance modulus and (D) phase for the different solvents. The curves shown are averages over n = 4 individual samples. (E) Bar plot of the impedance modulus at 1 Hz. Bar height: mean. Error bars: standard error. (F) Bar plot of the CSC values. Bar height: mean. Error bars: standard error. * p < 0.05, Mann–Whitney U test.
