Abstract
Pure and nano-ZnO doped PVDF-PMMA polymer blend-nanocomposites have been investigated for charge transfer effects in electrochemical sensors. Fourier transform infrared spectroscopy (FTIR) was used to characterize and elucidate the structure of the blended and doped polymers. Polymer microstructure and morphology were studied to establish the structure activity relations. Cyclic voltammetry (CV) furnishing information as a function of energy scan was the method of choice to test electronic properties of the modified polymers. Efficiency of CV results from its approach of rapidly observing the redox behavior of the analyte over a wide potential range. Electrode reactions of the intermediates and the products formed during the forward scan have been studied for sulphonamide azomethines. Comparative electro-activity of the PVDF-PMMA polymer blend-nanocomposite electrets electrode with the glassy carbon electrode was performed.
