An epoxy nanoporous composite (NPC) filled with hollow nanosilica exhibits lower permittivity than unfilled epoxy resin. The hollow nanosilica is a silica nanoparticle containing a nanometric closed pore. To investigate the effect of the closed pore

Film power capacitors are made out of polypropylene (PP) films co-wound with Al foil electrodes, impregnated with insulating oil. In a void, if any, or around the electrode edge, partial discharges (PDs) occur, leading to PP film deterioration and ev

Power generation output of dielectric elastomer generator depends on the relative permittivity of the elastomer sheet. High permittivity filler such as TiO 2 filler increases the permittivity of the elastomer sheet. In this paper, we investigated the

The feasibility of a permittivity-graded epoxy insulator with a low coefficient of thermal expansion (CTE) was clarified by evaluating the dielectric and thermomechanical properties of TiO2/SiO2 epoxy composites, which were epoxy composites co-filled

In order to investigate the effect of the large surface area of dispersed nanofiller on the breakdown strength, epoxy nanocomposites added with dispersed nanosilica, which has relative permittivity close to that of unfilled epoxy resin, needs to be p

The purpose of this study was to obtain epoxy/open nanoporous silica (ONPS) microcomposites whose permittivity was lower than that of the unfilled epoxy resin. The ONPS filler comprised silica particles containing nanometric pores that were open at t
