Outline of Final Research Achievements

Nanoscale molecular chain structures at the interfaces between solids and liquids are considered to have important roles in a wide range of fields such as functional materials and pharmaceuticals. However, the almost roles remain unclear because of the difficulty of direct observation of such molecular chain structures that exist only in quite small nanospace at the interfaces. In this study, we have established a method to visualize the spatial distribution of molecular chain structures and their dynamics by using a three-dimensional scanning atomic force microscopy (3D-AFM) technique.

Academic Significance and Societal Importance of the Research Achievements

ミクロな世界で生じている固液界面現象は摩擦、吸着、反応、溶解など目に見えるマクロ現象の起源となっています。固液界面に存在する分子鎖の構造・ダイナミクスを理解できれば、マクロな現象を原子・分子スケールで理解し、それを制御する技術に発展させることができます。これらを実現できれば、高効率エネルギーシステムや高機能な薬剤、環境浄化材料など社会問題解決に資する幅広い分野の材料開発に貢献できます。
