Abstract
This article deals with the dielectric properties of polydimethylsiloxane (PDMS) nanocomposites filled with SrTiO3 nanoparticles. The investigations were performed over a very broad range of frequencies (20 Hz to 3 THz). Almost no dielectric dispersion was observed in all the composites at room temperature over the entire range of measurement frequencies, and the dielectric losses were also very low under these conditions (3 interface and in the bulk polymer. The relaxation time for both cases followed the Vogel–Vulcher law, while the freezing temperature was substantially lower for relaxation at the PDMS/SrTiO3 interface.Keywords
