Outline of Final Research Achievements

Mechanical properties of polymeric materials are mainly determined by mechanical properties of polymer chains inside. Thus, experimental determination of mechanical properties of single polymer chain is important for widespread applications of polymeric materials. However, experimental techniques to measure the properties of single polymer chain have been still in development. In this study, we succeeded in extracting the mechanical properties of single polymer chain, especially its extremely stretched state, by analyzing the stretching and swelling tests of the macroscale polymer gels.

Academic Significance and Societal Importance of the Research Achievements

高分子材料は、ゴム・プラスチック・ハイドロゲルなどとして社会で幅広く使われており、高分子材料なくして現代科学技術は成り立たない。本研究では、高分子材料の構成単位である高分子1本鎖の(特に極限伸長状態における)力学的性質を、ゲルの力学的性質の解析から抽出することに成功した。こうして得られた情報は、高分子材料の力学的性質(強さ、伸びなど)を理解するために極めて重要となると期待される。
