Abstract

The dielectric properties of acrylic resin composites filled with BaTiO3, have been evaluated over a broad frequency range. These materials were used as models to study the dielectric response in polymer composite films for de-coupling capacitance applications. A series of photocurable resin formulations were prepared and photocured into films of approximately 100 μm to 120 μm thick. Dielectric permittivity of the materials was investigated at frequencies from 100 Hz to 10 GHz and temperatures from –140 °C to +150 °C. The dielectric constant of the composites reached 35 at 1 GHz. A high frequency dielectric relaxation process was identified and related to the molecular structure of the polymer matrix.
