Embedded capacitors can effectively decrease the size of electronic appliances. This application prefers the use of dielectric films with a high dielectric constant prepared by low-temperature processes. In the present paper, we report the preparation, characterization, and dielectric properties ranging from 10 kHz to 1 MHz of BaTiO3/epoxy and BaTiO3/Al composite films, processed at a low temperature. In the BaTiO3/resin composites, the ceramic content is limited and a maximum dielectric constant of 150 is obtained. A dense composite film of BaTiO3 particles having varying grain sizes and prepared by aerosol deposition showed a maximum dielectric constant of 400. However, BaTiO3/aluminum composite showed a high dielectric constant of >30,000 due to the percolation effect. |
