Abstract
A field grading material includes a field grading effective amount of a nanoparticle filler distributed in a polymeric matrix, and the nanoparticle filler is heterogeneously distributed in the polymeric matrix.
Claims16
A field grading material comprising:
- a polymer matrix, said polymer matrix having two or more polymer phases;
- and
- a field grading effective amount of a semiconducting nanoparticle filler, wherein said filler is heterogeneously distributed in said polymer matrix such that said semiconducting nanoparticle filler is well dispersed in at least part of one of said polymer phases;
- and wherein said semiconducting nanoparticle filler comprises less than 40% by volume of said field grading material.
A field grading material comprising a semiconducting nanoparticle filler heterogeneously distributed in a polymeric matrix, wherein a surface of said semiconducting nanoparticle filler is modified by treatment with an organosilane or organotitanate compound and said organosilane compound comprises an organic group selected from alkyl, alkylamino, amino and carboxy.
