摘要

太赫兹时域光谱是分析聚合物纳米复合材料优异性能机理的有效手段。由于纳米填料的存在，出现在2.7 - 3.1太赫兹频率处的介电吸收峰值频率向较低的频率移动，这似乎是由于聚合物基体和纳米填料之间界面处分子运动的限制。

Terahertz dielectric relaxation spectroscopy in polyamide nanocomposite

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.
