The D.C Electrical Properties of magnesium Filled Polymer Composites

In this paper the effect of filler content on D. C electrical properties of polyvinylchloride filled with magnesium powders has been investigated. For that purpose, the polyvinylchloride samples with magnesium additive prepared with different percentages and different thickness. The experimental results showed that the D. C conductivity of such composites increases suddenly by several order of magnitude at a critical weight concentration. The D. C electrical conductivity changed with increasing of temperature. Also the activation energy change with increasing filler concentration.
