Abstract

The influence of relaxation processes on electret properties of high-impact polystyrene (HIPS) free-standing films filled with titanium dioxide (TiO₂) of rutile modification are investigated by means of the combination of dynamic-mechanical and dielectric methods: thermally stimulated depolarization current (TSDC) measurements, thermally stimulated surface potential decay (TSSPD), dielectric relaxation spectroscopy (DRS), dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). Films with 2, 4, 6 and 8 vol.% TiO₂ as well as the pure HIPS are compared.
