Epoxy resin is widely used in high voltage apparatus as insulation due to its excellent mechanical, electrical and chemical properties. In recent years, researches on epoxy resin/nanocomposites have shown that the presence of nano-size filler in epoxy resin system can improve electrical, thermal and mechanical properties significantly. In the present paper, the epoxy resin containing nanosize SiO2...
Epoxy polymers reinforced with a premixed epoxy/nano-silica masterbatch or dry non-surface-treated nano-silica and ground micro-silica flour were compared. Cured plates of epoxy containing both nano-particles (up to 15 %wt) and micro-particles (up to 51 %wt) of silica were produced and tested. The glass transition temperature, Tg, of the epoxy was measured using differential scanning calorimetry (DSC),...
