摘要：
This paper deals with the study of the dielectric properties of polymer/high-k materials choosing an epoxy resin as the matrix and barium titanate (BaTiO3) or strontium titanate (SrTiO3) as micro-fillers (1 mu m in diameter). Different studies on epoxy/BaTiO3 and relatively few ones on epoxy/SrTiO3 composites showed the increase in the permittivity with an increase in the filler content (from 0 to 50 vol.%). Whereas several authors have already investigated the dielectric strength of epoxy/BaTiO3, little is known regarding epoxy/SrTiO3. In this paper, a comparison between these two types of composites will be presented. The main interest of SrTiO3 is that the dielectric strength of the bulk ceramic material is 7 times-higher (35 kV/mm) than that of BaTiO3 even though its dielectric constant is 10 times-lower (around 200-300).
