Convolutive cyclic voltammetry studies of PVA/CuI polymer composites at gold electrode

Cyclic voltammetry of PVA/CuI polymer composites was studied in acetonitrile as a solvent containing Tetrabutylammonium tetrafluoroborate (TBAFB). Cyclic voltammogram of PVA/CuI polymer composites exhibited unidirectional oxidative peak in the forward scan and irreversible reductive peak in the negative scan. The voltammetric behaviour explored that the electrode reaction of the investigated composite proceeds as EC mechanism. The highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) energy levels of the PVA/CuI nanocomposites were estimated from cyclic voltammetry. The chemical and electrochemical parameters of the investigated composite were determined and discussed using cyclic voltammetry, convolutive voltammetry and digital simulation methods. Key words: Polymer composite, polyvinyl alcohol, cyclic voltammetry, convolutive voltammetry.
