Modeling of Two-Phase Polyvinylidene fluoride polymer-based Nanocomposites for Energy Storage

Abstract

Polymer-based nano dielectrics are gaining a lot of attention in the scientific community. These materials, which are largely used in embedded capacitors, provide more viable energy storage alternatives. The goal of this study is to look at how electric fields are distributed in binary polyvinylidene fluoride (PVDF) based nanocomposites with various filler contents of TiO2 nanoparticles and MXene nanosheets. The aim of the work is the analysis of electric field distribution of nanocomposites using small and large permittivity value of nanoparticles in filler/ matrix of polymer system. Two-dimensional model with randomly distributed fillers in the polymer matrix was developed and COMSOL Multiphysics® software-based finite element approach was used to simulate the problem. According to numerical results, the binary nanocomposites with lower filler loading give a better distribution of the electric field. This research lays the path for high-performance capacitors to be developed.
