Abstract

A terahertz time-domain spectroscopic study was carried out as an effective measure to analyze the mechanism that induces superior properties in polyamide-6 nanocomposites. The peak frequency of dielectric loss appearing at about 3.0THz shifts to a lower frequency by the presence of clay nanofillers, while it is independent of the sample's mechanical drawing. Comparison of such behavior with X-ray diffraction spectra revealed that restriction of molecular motion is induced by the addition of nanofillers, which should play an important role in the superior properties.
