Abstract : Polymeric dielectric materials used for energy storage application should have essentially high dielectric constant, high energy storage density, low dielectric loss and retaining dielectric strength. The dielectric properties can be improved by adding suitable high permittivity nanoparticles into base polymeric material. The enhancement of dielectric properties of polymer nanocomposite mainly depends upon the inherent quality of nanoparticles and base polymer matrix. In this analysis of work Polyetherimide (PEI) and multi walled carbon nanotubes (MWCNT) are used as the base polymer and nanofiller respectively. PEI/MWCNT nanocomposite samples were prepared and experiments were conducted to measurement of dielectric properties with respect to various filler loadings. Simulation of electric field distribution in unfilled and nanocomposite are studied using Finite Element Method (FEM) and correlated with the experimental results. The significant improvement in dielectric properties of PEI nanocomposites is observed with lower concentration fillers and achieved the noteworthy improvement in dielectric properties.
