Because of the scarcity freshwater resources, fog collection as one effective methods to solve this issue has attracted widespread concern. Inspired by several natural creatures with capability collect water from fog, bio-inspired water-harvesting materials have aroused considerable attention and been widely developed. directional droplets transportation apex on both shorebirds beaks wheat awns, topological alloy net a V-shaped asymmetric geometry in its mesh was designed for collecting. Then, micro-/nano-hierarchical structures were modified surface netting wire via cathodic electrodeposition method. Thus, micro/nanostructures fabricated successfully. Through integration microstructure, not only water-collection rate is improved efficient drainage along designated pathways, but also clogging resolved. In addition, theoretical model constructed reveal mechanism, especially resultant force arising structure. This work provides insight into development novel fog-collecting materials, which potential applications other fields, such liquid transportation, microfluidics, interface science.
