Properties of electrochemically copolymerized aniline and melamine on functionalized multiwalled?carbon nanotube film electrodes

The electrochemical properties of polymerized aniline (PANI) and melamine (PMEL) that were copolymerized (PANIMEL) on a glassy carbon electrode (GCE) had been coated with functionalized multiwalled nanotubes (fMWCNT) to form PANIMEL/fMWCNT/GCE film studied, an aim toward energy storage (EES). A number factors, such as the choice working electrode, electrolyte, switching potential, applied scan rate, type fMWCNTs, initially investigated evaluated during individual polymerization via successive potential cycling. copolymerisation was then studied ideal monomeric ratio 1:3 gave optimal voltammetric peak current heights distinguishable redox potentials. Variable rate cyclic voltammetry (CV) electrosynthesized copolymer confirmed dominance surface-confined electron transfer process at electrode. stability also assessed revealed limited cyclability daughter polymeric melamine, which hypothesized be due excessive nitrogen content combined low porosity led poor ion intercalation-deintercalation mechanism. Electrochemical impedance spectroscopy (EIS) performed evaluate performance other control electrodes. corresponding EIS results suggested electrochemically superior PMEL/fMWCNT/GCE but inferior PANI/fMWCNT/GCE
