摘要：
Clarifying the effect of nanofiller material and particle dispersion on dielectric breakdown strength of epoxy nanocomposite contributes to the material selection, design and production. We prepared epoxy nanocomposites in which nanoparticles of silica, alumina, and titania were respectively dispersed, and measured their impulse breakdown strength. As a result, the improvement of the average breakdown strength of epoxy nanocomposites compared to epoxy resin was observed only in epoxy/titania nanocomposite, and it was clarified that the breakdown probability at low electric field on the Weibull distribution decreased by removing agglomerates in all the nanofiller materials. © 2022 The Institute of Electrical Engineers of Japan.
