Abstract
Disclosed herein are nanocomposite materials, devices thereof and methods thereof with a dielectric constant and corona resistance while having an increased or substantially maintained energy density, breakdown strength and/or dissipation factor relative to the polymer.
Claims43
A dielectric nanocomposite, comprising
- a continuous polymer phase comprising a polymeric material that exhibits a base corona resistance, a base dielectric constant (DK) value K1, a base energy density, and a base dielectric breakdown strength;
- and
- a dispersed particulate phase comprising a nano particulate inorganic filler material that exhibits a DK value K2, wherein the value of K2 is greater than K1 and wherein the nano particulate inorganic filler material is dispersed within the continuous polymer phase;
- wherein the nanocomposite exhibits a corona resistance that is greater than the base corona resistance of the polymeric material;
- wherein the nanocomposite exhibits an energy density that is not less than 65% of the base energy density of the polymeric material;
- and
- wherein the nanocomposite exhibits a dielectric breakdown strength that is not less than 80% of the base dielectric breakdown strength of the polymeric material.
