Abstract

Polymer composites of epoxy resin and Nb2O5 doped BaTiO3 were prepared in the form of film (thickness 30–300 μm) using a dipping technique. Samples containing various amounts of ceramic filler were examined by thermal analysis and SEM analysis. Dielectric measurements were performed from 20 Hz to 1 MHz and 20 °C to 120 °C. It was found that the final materials had high permittivities increasing with the filler concentration. Electrical relaxations were assigned to interfacial phenomena due to the particles and α-relaxation because of the resin.
