Results of electrical property characterization of various types of PP-SiO2 materials for DC capacitors are presented in this paper, focusing on breakdown strength and space charge measurements. They indicate that the nanofiller may influence the degradation rate of materials, modifying the space charge accumulation dynamics and extent, as well as the threshold field value for space charge accumulation. Statistical analysis of breakdown voltage shows that the presence of nanoparticles may also improve noticeably the breakdown behavior.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.139 No.2 （2019） 特集：2017 International Symposium on Electrical Insulating Materials本誌掲載ページ: 105-112 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/139/2/139_105/_article/-char/ja/
