摘要：

The layered permittivity graded material is achieved by making layered graded distribution of high permittivity fillers inside polymer matrix. In this study, we investigated the influence of the local electric field distortion by the high permittivity fillers on the surface field distribution of the layered permittivity graded material. In order to calculate the local field distortion of the high permittivity fillers, 3D calculation models for electric field distribution inside polymer composites with the high permittivity fillers were constructed by FEM (finite element method). As the high permittivity fillers, we assumed TiO2 particles with the spheroidal shape whose aspect ratio was 1.5 : 1. The filler distribution in epoxy resin was assumed lattice-like or random. The calculation confirmed that the electric field distribution on the surface of the layered permittivity graded material was affected by the local field distortion around the TiO2 fillers located close to the surface. This influence was clarified not to extend so far as the distance approximately 3 times of the TiO2 filler radius from the surface.
