Abstract:
1. A process for producing a nanocomposite material suitable for a power cable electrical insulation article comprising: providing a functionalized dielectric nanoparticle filler wherein the nanoparticle filler is at least one of silica, titania, kaolin clay, or magnesium oxide; drying the functionalized dielectric nanoparticle filler; compounding a polymer with the dried functionalized dielectric nanoparticle filler by imparting a shear force capable of preventing agglomeration of the nanoparticle filler, whereby the nanoparticle filler is substantially homogeneously distributed in the nanocomposite material; pelletizing the compounded nanocomposite material; melting the pelletized nanocomposite material; and, forming the insulation article.
