“…Conversely, there is a significant difference between the dielectric constant of the nanocomposite with varying dielectric constants of the polymer matrix, thus indicating that the dielectric property of the nanocomposite is indeed affected by the dielectric constant of the polymer matrix and nanoparticles, although the polymer matrix dielectric property plays a dominant role in this regard. These research results are consistent with the findings of the reported studies. , …”

A developed Rayleigh model that considers the effect of interphase properties is suggested to calculate the dielectric constant of polymeric nanocomposites. In this study, the nanofiller and its surrounding interphase are treated as an ideal particle, named as the equivalent nanoparticle. It has a core−shell configuration. Modeling results based on the developed Rayleigh model are confirmed experimentally, showing that the predicted dielectric constant is in accordance with experimentally determined values, which indicates the high accuracy of the developed model. In addition, the effects of nanofiller parameters and interphase properties along with base resin properties on the dielectric properties of polymeric nanocomposites are further explored. It can be found that the interphase region with a higher thickness and a higher dielectric constant will result in a polymeric nanocomposite with better dielectric constant. Simultaneously, nanofillers with a small diameter and a high volume fraction will increase the dielectric constant of nanocomposites. Furthermore, high dielectric constant polymer matrices and nanoparticles exhibit a positive effect on the dielectric constant of nanocomposites, while the dielectric constant of polymer matrices plays a leading role in the dielectric constant of nanocomposites. The developed Rayleigh model presents an efficient mathematical tool for predicting the polymeric nanocomposite's dielectric constant with different kinds of polymer matrix and nanofillers.

In this study, an optimized model is proposed for predicting the effective conductivity of nanocomposites, which contains conductive spherical fillers above the percolation threshold. The influence of filler properties, interphase regions, filler concentrations, elemental cell sizes as well as contact area on the effective conductivity of nanocomposites was investigated and discussed in detail.The developed model is verified by using the experimental data reported in the literatures, and it is found that the prediction results are fitted well with the experimental results at different particle concentrations. In addition, high levels of filler conductivity, particle concentration, and elemental cell size led to a good conductivity. The maximum conductivity of nanocomposite with σ eff = 1,500,000 S/m, V f = 0.07, r = 10 À4 nm, and D = 1250 nm is obtained at R i = 40 nm and d = 10 nm. Furthermore, the conductivity of nanocomposite is not sensitive to interphase thickness, when d is larger than 25 nm.
