  • Abstract

    Poly(methyl methacrylate) (PMMA) / ZrO2 composites were prepared by sol gel method. The structural, micro structural and the dielectric properties of the composites were studied using X- ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Hioki 3522-50 LCR Meter respectively. The electrical conductivity of composites has been investigated at different temperatures at frequency ranging from 50 Hz to 1MHz. The dielectric loss, dielectric constant and conductivity were changed with change in the concentration of ZrO2 and frequency of applied field. The electrical conductivities of the composites were found to increase with increasing temperature.
