Effect of the Microporous Structure and Nanoparticles on the Refractive Index and Dielectric Constant of Polymer Nanocomposites

The origin of the discrepancy between the calculated dielectric constants of polymers and experimental data has been considered. The differences are caused by the effect of residual amounts of the polymer synthesis products or the solvent used for producing films (plasticizing effect), or by the nonlinear terms of the Clausius–Mossotti function that have an effect on the dielectric constant. In the framework of the developed approach, the influence of nanoparticles on the refractive indices of some polymers and polymer nanocomposites has been evaluated.
