Abstract :
Terahertz time-domain spectroscopy was measured as an effective procedure to analyze the mechanism that induces superior properties in polymer nanocomposites. The peak frequency of dielectric absorption appearing at frequencies 2.7 - 3.1 THz shifts to a lower frequency by the presence of nanofillers, which seems to be ascribable to the restriction of molecular motion at the interfaces between the polymer matrix and nanofillers.
