Outline of Final Research Achievements

We synthesized a series of novel polyrotaxanes and pseudo-polyrotaxanes consists of poly(ethylene glycol)-b-poly(propylene glycol)-b-poly(ethylene glycol) triblock copolymer and β-cyclodextrin. The self-assembling structure and phase transition behavior of these materials were revealed by small angle X-ray scattering (SAXS), wide-angle X-ray scattering (SAXS). It was found that themacroscopic mechanical properties of polyrotaxane can be changed from a melt state to an elastic one by manipulating the ring positions.Another important finding was the self-assembling nanosheet structure made of pseudo-polyrotaxanes with a dimension of 10-20 nm thickness and 1-2 um size.

Academic Significance and Societal Importance of the Research Achievements

私たちの身の回りの様々な有機材料(個装材料、車の内装材料、タイヤ、容器、電子部品)などの硬さや割れにくさ、しなやかさ、耐熱性などの性質は、有機材料内部の分子の自己組織化(似ている分子がお互いにより集まる性質)によって大きく左右される。本研究ではポリロタキサンというネックレス状の新しい分子を用いることで、分子の自己組織化構造を操る新手法を解明した。
