Electrical Behaviour of Polyethylene Vinyl Acetate / ZnO Nanocomposite

Abstract

Recently, nanoscale materials have attracted material scientists because of their unique size depend-ent magnetic, optical, electrical and thermal properties. Homogeneous dispersion of nanoparticles in the polymer matrix and control of their size are vital to achieve many of these properties. In the present work, Zinc Oxide (ZnO) nanoparticles were prepared by solvothermal route. Chemical replacement reaction was chosen for the homogeneous dispersion of prepared ZnO nanoparticles into polymer matrix. Zinc oxide is an inorganic material with a large direct band gap (3.34 eV), high exciton binding energy (60 meV) and having a unique combination of properties. In inorganic/polymetric composite, the semiconducting nanoclusters enhances the electrical and thermal properties. The dielectric properties of the composites were studied using HIOKI 3532-50 LCR Hitester. The dielectric constant was found to increase with in-creasing the concentration of nano filler. DC electrical conductivity as a function of temperature was stud-ied using Keithley picoammeter 6485.
