Outline of Final Research Achievements

In this study, we have studied the physics of aqueous dispersion of cellulose nanofibers and conductive inks based on the approach that links experiment and theory such as microscopy movie data analysis. Thereby, we have revealed the fundamental characteristics of cellulose nanofiber dispersion in equilibrium, the difference of its drying process from equilibrium characteristics, spatio-temporal mechanism of the suppression of coffee-ring phenomenon by the addition of small amount of cellulose nanofibers, and the drying process of conductive polymer ink droplets on nanopapers.

Academic Significance and Societal Importance of the Research Achievements

本研究では,水という液体の中にブラウン運動しながら漂うセルロースナノファイバーや導電性ナノ粒子が,乾燥過程を通じてそれぞれナノペーパーや電気配線を形成するという,次世代産業応用上の重要な対象に関する力学現象を追究するものである.その場限りのレシピではなく,永続的価値のある力学現象の法則性に関する知見を獲得するのが本研究の重要な意義である.また,機械工学において伝統のある応用力学の真価を,統計力学と力学系の普遍的な視点に根差した,最先端の顕微鏡動画データ解析技術により発揮するものである.長期的な価値のある普遍的な知見を得ることは,具体的なモノを多岐に渡る産業応用に資する際にも拠り所となる.
