Abstract :
The subject of this study is dielectric properties of a four-component casting epoxy resin containing TiO2, Al2O3, WO3 and SiO2 nanofillers over the frequency range 20 Hz - 1 MHz with the aim to investigate the possibilities of using dielectric spectroscopy for diagnostics of such nanocomposites or structures constructed of them. Both positive and negative features of nanofillers in the epoxy resin are examined. The paper explains how to prepare samples for dielectric measurements, then proceeds with the presentation of results themselves before arriving to interpretations.
