| Outline of Final Research Achievements |
I elucidated improvement and the factor of insulation properties in polymer nano-composite materials to develop the hybrid model nano-composite materials which had both high thermal conductivity.
Effects of the addition of nano filler particles in the improvement of epoxy resin insulating characteristics were investigated and it has been clarified that surface erosion resulting from partial discharge (PD) could be substantially suppressed by the addition of several percent of nano filler content to epoxy composites.From the above experimental results, it can be concluded that one of the major mechanisms related to improving insulating performance via filler additions was the surface covering provided by filler deposition during the PD. In the case of nano filler composites, the outermost surface was more effectively and densely covered with filler particles during the PD.
