Polymer nanocomposite dielectrics

Polymer nanocomposites not only exhibit advantageous electrical, magnetic, optical properties of nanomaterials but also have the advantage of easy molding of polymer and therefore great attentions are now paid to the research of them. This paper summarizes the recent advances of the researches on the dielectric properties of the polymer nanocomposites, and especially deals with the investigation results concerning the electrical conduction, dielectric strength, space charge, dielectric permittivity, dielectric loss and partial discharge. The aspect of the future research work is proposed.
