Abstract
In this study, (Zn0.5Ta0.5)0.02Ti0.98O2/polyvinylidene fluoride (PVDF) composites were fabricated and their dielectric properties were analysed up to 1 MHz. The ceramic filler material was synthesized by the solid-state ceramic route and the phase purity was confirmed by X-ray diffraction. Composites with different volume fractions were prepared by finely dispersing the filler in the PVDF matrix followed by compression moulding. The PVDF phase was confirmed by Fourier transform infrared spectroscopy. Dielectric properties (dielectric constant and loss tangent) up to 1 MHz were studied using an impedance analyser. A dielectric constant of 63 along with an acceptable loss of 0.028 was obtained for a filler volume of 50% at 1 MHz. Also, a dielectric constant of 78 with a loss of 0.14 was obtained at 30% filler loading at 1 kHz.
