Investigation of Optical and Electrical Property of Polyaniline-Zinc Ferrite Nanocomposites

Abstract

Zinc Ferrite nanoparticles are synthesised by solution combustion method with urea as fuel. The prepared ferrite nanoparticles are added to the Polyaniline polymer during chemical oxidative polymerization to get Polyaniline-Zinc ferrite nanocomposites in different weight ratios(10%, 30% and 50%).XRD confirms the formation of the nanocomposite as the XRD spectrum of the composite has Characteristic sharp peaks of zinc ferrite and the characteristic broad peak of Polyaniline. From the UV-Vis absorption data, the optical direct band gap is estimated with the help of Tauc plot and the obtained optical band gaps are found to decrease as the content of Zinc ferrite inpolyaniline composites increases. DC conductivity increases as the percentage of zinc ferrite increases in the polyaniline matrix.
