Electrochemical impedance spectroscopy (EIS) measurements
were performed in a monomer-free electrolyte solution with the
perturbation amplitude of 10 mV on the Al1050 electrode over the
frequency range of 10 mHz to 100 kHz with the IviumStat potansiostat/
galvanostat. Open circuit potential was used in all experiments
and modified polymer films were allowed to equilibrate for 10 min
at each potential before the measurements
