摘要：
Water collection from humid air is a key technology for freshwater acquisition and dehumidification, and the design of functional surfaces with excellent water collection capability is critical. Enhanced biomimetic structure was proposed in this study according to the cluster space distribution near wall for humid air condensation. The experimental results show that the existence of spatial structure promotes the evolution and nucleation of clusters, which enhances water-collecting ability of the surface. Porous copper pillars were used to simulate ciliary structures distributed on geranium surface (with the height of 300 μm) and enhance capture and nucleation of cluster. The results show that the water collection capability of the hydrophobic porous copper pillar reaches 140 mg∙cm-2∙h-1, which is 2.4 times that of the smooth surface. This work can provide new idea for the design of water collection surfaces in high humidity areas. © 2023 Zhejiang University. All rights reserved.
