POLYOLEFIN-BASED HIGH DIELECTRIC STRENGTH (HDS) NANOCOMPOSITES.

摘要

The present invention is a cable having (a) one or more electrical conductors or a core of one or more electrical conductors and (b) each conductor or core being surrounded by a layer of insulation. The insulation layer is prepared from a composition comprising a polyolefm and a 3 -dimensional, cage-structured nanoparticle. The preferred polyolefins are polyethylene polymers, and the preferred nanoparticles are polyhedral oligomeric silsesquioxanes (POSS), polyhedral oligomeric silicates (POS), or polyhedral oligomeric siloxanes.
