Electrochemical impedance spectroscopy characterization of PEDOT/GO coated CFEs. (a) Average impedance measurements of (n=3 individual electrodes for each deposition duration) over a 1–100,000 Hz sinusoidal current frequency range. (b) The average impedance at 1 kHz sinusoidal current frequency is significantly altered by PEDOT/GO deposition duration (* one-way ANOVA: F(4,14)=234, p<1e−9).
