Abstract :
The zinc oxide (ZnO) nano particles of size 40 nm are synthesized by sol gel method used as filler in polyvinylidenefluorid (PVDF) to develop PVDF- ZnO nanocomposite. The thermally stimulated discharge current (TSDC), tangential loss and permittivity were observed in 204 m thick samples at different experimental conditions. The TSDC of all nanocomposite samples is characterized by single peak located between 135degC to 150degC. The permittivity and loss tangent decreases with frequency ranges from 1 kHz to 5 kHz at 60degC. This paper describes the change in electrical properties of PVDF by introducing the ZnO nanoparticle in polymer matrix.
