Emad Abbas Jaffar Al-Mulla

Abstract

Grafted polystyrene with acrylonitrile modified nanoparticles of TiO2-ZnO was successfully prepared to study its electrochemical characterization by cyclic voltammetric (CV) method. It was found the new modified copolymer had good electrochemical properties and was a semi-conductor material. The ratio redox current peak (Ipa/Ipc) was equal to 2; the separation potential peak (Epa-Epc) was equal to 113 mV. Normal saline was used as a good electrolyte to enhance the solution of peaks of redox current for K4Fe(CN)6. Different concentrations, scan rates, and pH values were studied of the modified glassy carbon electrode (GCE). Diffusion coefficient values of the ions were determined using Randles-Sevcik equation. Scanning electron microscope (SEM) and atomic force microscope (AFM) images for the new grafted polymer modified nanoparticles were studied. The product could be used in various industrial applications due to its electrochemical properties.
