However, conventional hydrophobic membranes are limited to treat only relatively clean water sources with minimum surface active agents, which causes the loss of clean water source and valuable resources in wastewater. Omniphobic membranes that repel both water and oil are therefore imperative to be fabricated for extended cases in membrane contactors. Despite the potential of omniphobic membranes, studies on the fabrication of such membranes are rather scarce. Therefore, the main object of the three-year project is to design several strategies to engineer surface energy and nanostructures for the fabrication of omniphobic membranes. In the first project year, we will focus on designing omniphobic glass fiber membranes through comparative study to elucidate the key factors that determine surface omniphobicity. In the second project year, omniphobic hollow fiber membranes will be prepared using the methods developed in the first year. Atomic layer deposition of intrinsically hydrophobic rare earth oxides will be used as an alternative way to lower the surface energy and increase the robustness of membranes. In the last project year, the omniphobic membranes will be tested in membrane contactors. Moreover, the omniphobic hollow fiber membranes will be highly-packed in a bundle to realize scaling-up for industrial applications.全疏膜薄膜接觸器原子沉積法中空纖維膜稀土氧化物Omniphobic membranesmembrane contactorsatomic layer deposition (ALD)hollow fiber membranesrare earth oxides
