Synthesis and characterization of Polyvinylidiene Flouride–Ba0.7Sr0.3TiO3 Nanocomposites

Abstract

The Lead free, Barium Strontium Titanate Ba0.7Sr0.3TiO3 has been synthesized by Sol-Gel method. The synthesized sample has been subjected to the structural, morphological studies. The formation of the compound has been confirmed by XRay diffraction (XRD) analysis. The X-Ray Diffraction study confirmed that Ba0.7Sr0.3TiO3 has tetragonal phase with crystalline size 30.53nm. The SEM studies have shown the good morphological structure and the average grain size of Ba0.7Sr0.3TiO3 has been found to be 1.9 μm. The polymer ceramic composites have prepared using Polyvinylidene fluoride (PVDF) as polymer matrix and Ba0.7Sr0.3TiO3 (BST) as ceramics powder by Solution Casting method. The surface morphology and thermal study of the BST/PVDF composites with different loading percentage have been done by the SEM and DSC.
