The A.C Electrical Properties of (PVC-Sn) Composites
Abstract:The A.C electrical properties of randomly mixed insulator – conductor system consisting of polyvinylchloride (PVC) as insulator and tin (Sn) as conductor powders were studied. The effect of tin concentration and frequency of applied electrical field on the A.C electrical properties of (PVCSn) composites have been investigated. The experimental results show that the dielectric constant of the (PVC-Sn) composites decreases with increasing frequency, and then increases suddenly by several order of magnitude at a critical weight concentration. The dielectric loss oscillatory with increasing frequency, increased with the tin content. The A.C electrical conductivity of the (PVC-Sn) composites increases with the increase of the frequency, and then increases suddenly by several order of magnitude at a critical weight concentration.
