On the degree of exfoliation affecting the corona performance of a nanodielectric surface

Abstract

Samples of a nanodielectric material were synthesized. This bulk material was a mix of epoxy resin, a SiO2 load and a small fraction of inorganic nanoparticles. The present experiment aimed at determining the effect of the degree of exfoliation on the performance of the nanodielectric surface when exposed to partial discharges. It was found that when the degree of intercalation/exfoliation of the nanoclay is low, the nanodielectric surface did not exhibit superior performance compared to that not containing nanoclay.
