Dielectric studies on hybridised PVDF-ZnO nanocomposites

Nanocomposites of polyvinylidene fluoride (PVDF) and nano-ZnO were prepared using the solution casting method for different concentrations of nano-ZnO and were characterised by X-ray diffraction and atomic force microscopy. Optical properties of these nanocomposites were determined by using UV-Vis absorption spectroscopy and Fourier transform infrared analysis. The variation of dielectric properties such as dielectric constant, dielectric loss and electric modulus of the hybrid films based on the content of ZnO studied for various microwave frequencies at room temperature showed that the dielectric constant of PVDF-ZnO hybrid films increased with increasing ZnO content at room temperature.
