Pure PVDF films have a high dielectric constant compared to other dielectric polymer films, although the use of PVDF-based nanocomposite films further enhances their properties and makes them promising for various energy storage applications. In this research, the dielectric constant of PVDF nanocomposites was calculated using parallel, series, Lichtnecker and EMT models which are based on the volume fraction of nanoparticles, and consequently, the results were compared with the experimental sets of data obtained from the relevant literature. The results showed that the Lichtnecker and EMT models with a shape factor of 0.1 are more accurate in predicting the dielectric constant of PVDF nanocomposites in comparison to the other models used in this study. On the contrary, the parallel model predictions showed the highest deviation from the dielectric constant values of PVDF nanocomposites reported in the literature.
