Outline of Final Research Achievements |
Liquid transportation is of great technological significance in industrial or biomedical use including infrastructure and printed electronics. Liquid transportation typically relies on nano/microscale structural anisotropy and/or chemical structures, which induce a guide of liquid to desirable route. However, undesirable adhesion losses in transporting liquid are inevitable and it results a decrease of the transport efficiency, or increasing a risk of infection by contamination. In this work, we introduce a novel liquid manipulation strategy to design non-sticking liquid transportation based on hydrophobic materials. We observed the adhesion dynamics of liquid on solid surfaces with different wettability and structures. This observation offered us a strategy to design non-wetting liquid transportation.

Academic Significance and Societal Importance of the Research Achievements |
液体の輸送過程における不本意な付着残りは、液体の輸送効率の低下だけでなく付着容器の汚染を生み出す。このような液体の付着を抑え、輸送効率を高める研究は、医療現場や食品の容器への付着などのフードロスや、廃棄液体の環境汚染問題への解決策として注目を集めている。本研究ではこのような液体の不本意な付着を抑制する撥水技術を基盤とした液体の輸送技術の開発に着手した。本課題を通じて液滴の付着ダイナミクスを明らかにし、得られた知見をもとに液滴をマイクロリッタースケールからリッタースケールまで付着損失なく任意方向に遠隔輸送できる技術を開発した。
