Investigations into the morphology of nano-silica dispersion in epoxy resin, along with quantum chemistry based simulation analysis to the models of NC-hydrophilic and NC-hydrophobic, suggest that the formation of a network structure by hydrophobic nano-silica may lead to the observed excellent properties of NC-hydrophobic on fracture toughness and treeing resistance. Moreover, the homogeneous dispersion of nano silica achieved by hydrophilic nano-silica in NC-hydrophilic is considered to be the optimal condition to improve partial discharge resistance.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.133 No.2 （2013） 特集：パルスパワーの生体作用と医・農・水・環境への先進応用本誌掲載ページ: 57-63 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/133/2/133_57/_article/-char/ja/ Show more
