Estimation of AC Breakdown Strength of Epoxy/TiO2 Nanocomposite using Electron Avalanche Breakdown Model

Large agglomerates are dielectric defects in nanocomposites, which are polymer matrix added nanoparticles. However, a method for quantifying the critical agglomerate size to improve the dielectric breakdown strength of nanocomposites has not yet been established. In this study, the dependence of the AC breakdown strength on the agglomerate size of epoxy/TiO
