Dielectric Properties of Al₂O₃Nanofibers/Epoxy Resin Nanocomposites

Abstract:

In this article, Al₂O₃ nanofibers have been successfully synthesized by hydrothermal process and Al₂O₃ nanofibers/epoxy nanocomposites were fabricated by incorporating the Al₂O₃ nanofibers modified by 3-aminopropyl trimethoxysilane (APTMOS). Dielectric spectra of the nanocomposites were investigated. The effects of Al₂O₃ morphology and concerntration on dielectric spectra of nanocomposites were discussed. The results showed that the dielectric constant increased smoothly as the alumina nanofibers concentration increasing, but it decreased with increasing frequency. While the dielectric loss increased slightly with increasing frequency, however, it still remained at a low level.
