Study of AC electrical properties of (PVA-PEG-Sb2O3) Composites

Abstract The aim of this study is investigation of AC electrical properties for (PVA-PEG- Sb₂O₃) composite material at different frequencies which they ranged from 100Hz -6MHz. The PVA-PEG- Sb₂O₃ composite prepared using solution casting method. The experimental results have shown that the dielectric constant(ɛ) and dielectric loss (δ) decreases with increasing the frequency, it also appeared that ɛ and δ are increased with the increasing of antimony oxide (Sb₂O₃) content. The electrical conductivity (σ) increased with the increasing of frequency and decreased with the increasing of Sb₂O₃content in the PVA-PEG- Sb₂O₃composites.
