Electrical properties of a polymeric nanocomposite with in-situ synthesized nanoparticles

Nanocomposite electrical insulation materials (nano-dielectrics) have been the focus of dielectrics research for the last ten years. Different materials preparation (mixing) methods have been applied to fabricate novel nanocomposites with improved electrical insulation properties. In this contribution we describe a nanodielectric fabrication method where the base polymeric material is loaded with particles, which are synthesized "in-situ". This method has an advantage in dispersing nanoparticles over other nanocomposite processing methods, because the particles are synthesized in randomly distributed sites inside the polymer network. In this paper structural and electrical properties of nanocomposites of polyvinyl alcohol and titanium dioxide are presented.
