Development and Performance Analysis of High Energy Density Thin Film Capacitors with Ag/Pva Nanocomposites as Dielectric Medium

Abstract

In recent years, the need for light weight, compact, high energy density capacitor increases rapidly for applications in various household as well as industrial appliances. The previously used monolithic materials are reaching a plateau in terms of energy storage capabilities due to the trade-off between dielectric constant, dielectric loss and voltage breakdown. The metal polymer nanocomposites have the potential to overcome these limitations through a synergistic coupling of high dielectric constant nanoparticles in high dielectric breakdown polymer matrices based on their characteristics like Coulomb Blockade Effect, Interfacial Polarization Effect etc. Here, we present the synthesis and characterization of Ag/PVA nanocomposites and investigate the dielectric properties of these materials in thin film capacitors in terms of energy density, dielectric constant and dielectric loss.
