The flask containing DEB, [NBu4][PF6], and DCM was sealed with a rubber septum, covered with aluminium foil during a coating experiment, and flushed with nitrogen for 10 minutes. We prepared a fresh solution each day of the experiment, and for coating each electrode, the required amount was withdrawn from the stock using a glass syringe. We placed a CFM of the desired length along with a pseudo-Ag/AgCl electrode in an amber, septum-capped 20 mL vial containing approximately 10 mL of the above stock. We flushed the entire vial for 10 min with nitrogen or until we observed condensation outside the vial. We then applied the waveform from -1 V to +1.9 V at a scan rate of 100mV/s using the Wavedriver 100 Potentiostat (Pine Research Instrumentation, Durham, NC). We performed these waveform applications either once (which we will denote later on as "1 scan" or "single scan"), twice (2-scan), or thrice (3-scan).
