Abstract

Nanocomposites have been emerging as important materials for high voltage applications due to the influence conferred upon the polymer by the nano-filler. However, the formation of nanocomposites is frequently hindered by the incompatibility between the polymer and filler, resulting in poor dispersion of the nanofiller and creating an inhomogeneous and irreproducible material unsuitable for use. One method for achieving dispersion of the polar montmorillonite nano-clay in non-polar thermoplastics is through grafting organic moieties to the nano-clay via ionic exchange. The effects of adding such nano-clays to polyethylene, polypropylene and polystyrene in terms of dielectric breakdown behavior and frequency dependent permittivity are investigated and compared herein.
