| Abstract |
プラスチックの結晶化やゴムの応力軟化など、高分子材料の物性変化を動的に捉えることができるテラヘルツ分光計測装置を開発した。同装置を用いて高分子ポリ乳酸薄膜試料の加熱実験をおこない、ガラス転移や結晶化前後におけるテラヘルツ誘電応答の時間変化を捉えることに成功した。また、黒色ゴム試料の延伸に伴うテラヘルツ周波数領域の誘電応答の変化を調べ、試料内部に含有されているカーボンブラック凝集体の形状変化を推測することにも成功した。
We have developed a terahertz spectroscopy system to dynamically capture the changes in physical properties of polymeric materials, such as crystallization of plastics and stress softening of rubber. We succeeded in capturing temporal changes of terahertz dielectric responses of polylactic acid film sample before and after the glass transition and crystallization after heating the sample. We also succeeded in inferring the shape change of carbon black aggregates contained in a rubber sample from a dielectric response change in terahertz frequency region caused by stretching the sample.
