Interfacial dielectric relaxations have been studied in composites made with epoxy resin and copper or iron particles. Over the temperature range reported (20-160 °C) relaxation peaks are formed in the 10-10 3 Hz frequency range. They are attributed to the Maxwell-Wagner-Sillars (MWS), or interfacial, polarization effect, created in heterogeneous dielectrics. The observed MWS loss peaks shift...
