Abstract
Preparation and characterization of pure and nano-ZnO doped PVDF-PMMA polymer blend-nanocomposites for investigating the charge storage and transfer effects have been studied. Fourier transform infrared (FTIR) was used for characterization and structure elucidation of the blended polymers. Polymer microstructure, chain conformation and polymer morphology were studied to establish the structure activity relations. Cyclic voltammetry (CV) was chosen to study the electronic properties of the modified polymers as it furnishes information as a function of an energy scan. The effectiveness of CV results from its capability 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 analogues of synthesized azomethines. Comparative electro activity of plain glassy carbon electrode and the PVDF-PMMA polymer blend-nanocomposite electrets modified electrode was studied.
