| Outline of Final Research Achievements |
This study aims to develop novel liquid transport systems with high efficiency and selectivity by structural optimization and wettability control. We fabricated a series of water channels on silicon wafer by photolithography mimicking those on legs of Ligia exotica. These channels are able to transport oil against gravity with its surface oleophilicity just like Ligia exotica uptake water. In addition, these channels turn out to uptake water after surface oxidation by vacuum UV light irradiation. This suggests that surface structures of these channels enhance the inherent wettability of the surface and combining surface chemistry with surface structure enables these channels to transport a variety of liquids. Moreover, it was revealed that channels have both hydrophilic and oleophilic regions can separately transport oil and water upward from a mixture of oil and water.
