Abstract

Polypropylene (PP) which is recyclable and easy to process, has the potential to be a promising alternative for conventional cross-linked polyethylene (XLPE) for using in high voltage power cable insulation. This paper aims to determine the effects of different types of nitride-based nanoparticles on the dielectric and mechanical properties of PP. Thus, three nitride-based fillers, boron nitride, aluminium nitride and silicon nitride are selected. To evaluate the influence of different filler concentrations, PP nanocomposite systems containing 5 or 10 wt.% of nitride-based nanoparticles were prepared by a modified solution blending method. Meanwhile, 5 g of neat PP was made with the same procedure to be the reference system. For determining the most suitable fillers in terms of electromechanical properties, three experiments namely, AC breakdown, dielectric spectroscopy and tensile test were conducted. The results of these experiments indicate PP with 5 wt.% of boron nitride has the best performance on dielectric and mechanical properties among nanocomposites.
