摘要：
BaTiO/epoxy composites consisting of two three-dimensionally interpenetrating networks of BaTiOand epoxy phases were prepared using a new approach. The BaTiO/epoxy composites exhibit a colossal dielectric constant, low dielectric loss and high flexural strength. In the BaTiOnetworks, chemically bonded grain boundaries between neighboring BaTiOgrains were established, and they are responsible for the colossal dielectric constant and high flexural strength of the BaTiO/epoxy composites. Furthermore, unlike the conventional ceramic/polymer composites, this approach also makes high loadings of BaTiOcontents possible for the BaTiO/epoxy composites without compromising their high flexural strength.
