It has been concluded that the enhanced electrical properties of nanocomposite dielectrics (nanodielectrics) are mainly contributed by the phase interface regions which are attributed to the large specific surface area of the nanoparticles. This research introduces zeolite nanoparticles as the nano-fillers with microporous structures to obtain more phase interface regions and further improve the electrical...
This paper describes the effects of KH550 as surface treatment agent of nano-Al2O3 on the properties of modified cellulose paper. Samples in five groups were respectively prepared by different processes, and the performances of these samples were comparatively analyzed. Based upon the liquid doping method, the maximum tensile strength, breaking elongation rate as well as AC breakdown strength respectively...
We report here dielectric constants of epoxy doped with Gama phases of 1-9 phr Al2O3, and dielectric constants and breakdown field measurements of Polyimide doped with Alpha phases of Al2O3 in 1-7 weight %. With enough doping, the imaginary part of dielectric constant increases till GHz range, and then decreases as frequency increases, and rebound to DC value. The breakdown field of nanoparticles...
The treeing-like breakdown in low density polyethylene (LDPE) samples can be induced by electron beam irradiation without applied field. Pure LDPE samples and LDPE samples doped with inorganic nano-powder (0.5%wt) are used in our experiments. A steel needle electrode is inserted into each sample for about 3mm depth before irradiation. Samples are cut into slices whose surfaces are perpendicular to...
