| Research Abstract |
In order to clarify the applicability of nanoporous composite to electric power apparatus, lower permittivity mechanisms and dielectric breakdown characteristics was investigated. It was revealed that Mesoporous-alumina/Epoxy nanoporous composite had lower permittivity than nonporous composite due to its particle porosity. Furthermore, it was revealed that each dc breakdown strength of mesoporous composite and nonporous composite was almost followed on one tendency as a function of volume concentration of filler. The above results revealed that the nanometric pore inside the mesoporous particles could not be critical defect for dc dielectric breakdown characteristics. Nanoporous composite material has the possibility of the effective insulating material for next generation electric power apparatus.
