Résumé
Abstract An accurate three-dimensional (3D) model was developed using hybrid analytical finite element method (H-FEM) for the simulation of frequency-domain dielectric response of low-density polyethylene (PE) filled with titanium dioxide (TiO 2 ) nanoparticles. The input values of dielectric permittivity of nanoparticle and interphase were calculated analytically using the mixture model and adjusted by an optimization procedure. The effective permittivity of PE/TiO 2 nanocomposites was then modelled by COMSOL Multiphysics. The model output results agreement with the experimental values indicate that the developed H-FEM 3D model is suitable for use in solving dielectric response problems of different nanodielectric materials in frequency domain. Furthermore, the simulation results also offer further understanding into the effect of the nanoparticle interphase on the final dielectric properties of the nanodielectric materials.
