Abstract
First the frequency-dependent dielectric spectrum of a self-assembled pure \(\hbox {BaTiO}_{3}\) (BTO) nanocrystalline thin film with consideration of the packing density is studied using the Lichtenecker logarithmic rule and the modified Kerner model. Then the Wiener lower bound is modified to evaluate the overall effective dielectric properties for 2–2 type of layered nanocomposites within a large frequency range, and a simple rule of mixture is found to be suitable for predicting the dielectric permittivity of multi-layered composites. The calculated dielectric properties of the BTO/parylene nanocomposites agree reasonably well with the experimental data, whereas a little discrepancy in the dielectric loss tangent is shown in the frequency range beyond \(10^{5 }\hbox {Hz}\).
