Abstract
In this study, some electrical properties (electrical conductivity, specific resistance, molar conductivity and degree of dissociation) were measured for natural polymer SMR20 with (molecular weight 350168 gm/mol) and impurities 5% ZnO nanoparticle, the polymer that have been used in Babylon tyres Factory. The aim of this study was to test the efficiency of the polymer in electrical industry under Iraqi environment conditions specially under the high temperature degrees so that the measures were under different temperature degrees (25, 35, 45, and 55) πc.Results revealed that most electrical properties increased with increasing of concentrations of polymer solved in toluene and temperature degrees except the specific resistance property which declined under high concentrations and temperature. The nanoparticle which was used in this study significantly enhanced the electrical properties. These results could be attributed to the binding between polymer molecules itself from one side and also the binding between polymers and solvent and with nanoparticle molecules from the other sides. Because of these limited changes, the polymer would be suitable and safe to be used in the electrical industry, while the remarkable enhancement of electrical properties enable the polymer for using in super generations industry.
