Research Abstract |
Effects of nanofiller addition on several dielectric properties were evaluated for various polymer nanocomposites. Conductivity of epoxy resin is unchanged by the SiO_2 nanofiller loading, but it increases if AlO(OH) nanofillers. In the case of polyamide, carrier transport is restricted by the nanofiller loading and the relaxation time becomes longer by the nanofiller loading for several relaxation processes. Molecular motions involved in each relaxation seem to be restricted by the nanofiller loading. Photoluminescence and absorption spectra indicate that localized states are not induced by the nanofiller loading. Moreover, ultraviolet absorption and THz spectra are obtained for various electric insulating materials and assignments of some of the peaks observed are carried out using numerical calculations based on the density functional theory.
