Influence of Adding Nano Particles on Dissipation Factor and Volume Resistivity of Polymer

Abstract

Nowadays the polymeric insulators with Nano fillers have a lot of attention of researchers and developers. Inorganic Nano-fillers are added to the polymer to improve some insulation properties. In the present work, the dissipation factor and volume resistivity of liner low-density polyethylene (LLDPE 324CN)-based SiO2 and Al2O3 Nano fillers were investigated. The two nanomaterials (SiO2, Al2O3) were separately added to the polymer with different concentrations (0.5%, 1.5%, 3%, 6%). Also the mixture of the two nanomaterials was also added together to the polymer. Based on the experimental measurements, it is found that the addition of inorganic Nano fillers on the polymer can improve the dissipation factor and volume resistivity. At 6% of SiO2, the volume resistivity can exceed three times that of unfilled polymer while. 6% of AL2O3 increases by more than 34% compared with unfiled polymer.
