Outline of Final Research Achievements

This work aims at the development of novel methodology for the structure analysis of polymer materials at the single chain level by the combination of super-resolution optical microscopy (SROM) and grazing angle neutron small angle scattering technique (GI-SANS). For SROM, the newly developed phase mask enabled the three-dimensional observation with the spatial resolution of about 20 nm. Moreover, by the introduction of a neutron focusing mirror, the sensitivity of the GI-SANS measurement was improved 6 times compared to the previous system. The combination of the SROM and GI-SANS developed here would provide the further insight of the polymer materials.

Academic Significance and Societal Importance of the Research Achievements

高分子材料中のナノ構造を評価するためには、顕微鏡による実空間観察と散乱法による逆空間観察が行われるが、それぞれに長所・短所があり、これらを相補的に利用することが必要である。本研究においては、バルク中の単一高分子鎖までを観察可能な方法論を示した。これにより高分子材料の内部構造の精緻解析が可能となり、材料の基礎物性の解明に貢献するものと考えられる。
