A comparison of molecular and nanodielectrics for HV insulation application

Published work, including mechanistic studies, of molecular dielectrics, involving molecular additives, co-polymers, and miscible and immiscible polymer blends, in the 60s, 70s, and 80s, led to major improvements in breakdown and physical and mechanical properties of polymer-based insulation systems. Many new products were the result of these studies, resulting in improved designs and performance. A comparison is made between these molecular dielectric materials, and new nanodielectrics, to assess each of their advantages and disadvantages. Based on this comparison, potential avenues for improvement of nanodielectrics are identified.
