Abstract

Poly vinyl alcohol (PVA) / TiO₂ 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 5 MHz. The electrical conductivities of the composites were found to increase with increase in TiO₂ concentration and with increasing temperature.
