Abstract
- To endow excellent dielectric properties for embedded capacitors application, high-permittivity BaTiO3/polyvinylidene fluoride (BT/PVDF) nanocomposites with sandwich multi-layer structure were fabricated via a spin-coated and hot-molding technique. Dependences of dielectric properties of the BT/PVDF multi-layer nanocomposites on frequency and temperature were studied. Results show that concentration and dispersion of BT particles in multi-layer structure nanocomposites had an obvious influence on the final dielectric permittivity. Influence of the compatibility between adjacent layers on dielectric permittivity was also discussed. We use the effective-medium theory and capacitance series model to predict the theoretical values of the dielectric permittivity of the nanocomposites. [ABSTRACT FROM PUBLISHER]
