Sigma-Aldrich, Germany supplied us with Ag/AgCl reference electrode double-junction for potentiometric measurements, while pH adjustment is done using a Jenway 3505 pH meter (Staffordshine, UK). Digital ion analyzer (Jenway, United Kingdom) Magnetic stirrer was used. Potentiostat/galvanostat PGSTAT204 (Metrohm Autolab, Netherlands) controlled using Nova 1.11 software was used for electropolymerization and electrochemical.
TLC aluminum plates F254 (20 × 20 cm2) with 0.25 mm thickness layer, E. Merck (Darmstadt, Germany) was used for oxidative degradation monitoring, and Micro-droppers was used for sample application on plates and spots visualization, for degradation tracing using a 254.0 nm UV lamp.
