All electrochemical measurements were carried out on the BioLogic SP-150 potentiostat (France). The devised flexible electrode served as working electrode (WE), platinum plate as a counter electrode (CE) and silver wire with electrodeposited AgCl layer as quasi-reference electrode. WE and CE were mounted parallelly in special electrochemical holder fabricated at IPC PAS . A Carl Roth, Germany vial was used as the electrochemical vessel, cut for measurements to a volume of approximately 3 mL. All curves presenting the results of electrochemical measurements were smoothed in the OriginLab 2020b software using the Savicky-Golay method with 10 points of window. All experiments were carried out at room temperature of the laboratory, reaching an average of 25 °C.
