Abstract

In the present research work, we have synthesized the ferroelectric ceramic Ba0.7 Sr0.3TiO3 (BST3)/PVDF (Polyvinylidene difluoride). Polymer nanocomposites for energy storage applications, designed to synergistically combine the high dielectric permittivity of hydroxylated barium strontium titanate (hy-BST3) with the mechanical flexibility and electroactive properties of poly(vinylidene fluoride) (PVDF). Hydroxylated Barium Strontium Titanate (hy-BST3) has been synthesized using the sol-gel combustion method followed by surface hydroxylation using H2O2 to achieve nanoscale particles with improved uniformity and reduced agglomeration. BST3/PVDF nanocomposites have been synthesized using the solution casting method with 90 wt. % PVDF polymers as a matrix and 10 wt.% BST3 ceramic as nano,fillers and their dielectric and energy storage properties have been investigated. The solution casting method is a technique used to synthesize nanocomposites in film form. The influence of hy-BST3 and BST3 content on the dielectric constant, dielectric loss and energy storage properties were systematically evaluated. The results reveal that the incorporation of hy-BST3 significantly enhances the dielectric constant of PVDF while maintaining relatively low dielectric loss. XRD analysis has been performed to check the successful synthesis of nanocomposites. We have obtained improved dielectric and ferroelectric properties in the case of hy-BST3/PVDF nanocomposite, which makes it better for energy storage applications requiring high energy density, reliability and mechanical flexibility.

Keywords: Ferroelectric, Nanocomposites, Solution casting method, PVDF, BST3, Energy storage density.
