Abstract：
Water scarcity has become a critical global threat, particularly in arid and underdeveloped regions. However, certain insects and plants have evolved the capability to obtain water from fog under these arid conditions. Bionic fog collection, characterized by passive harvesting, minimal energy requirements, and low maintenance costs, has proven to be an efficient method for water harvesting, offering a sustainable water source. This review introduces two superwettable surfaces, namely, superhydrophilic and superhydrophobic surfaces, detailing their preparation methods and applications in fog collection. The fog collection mechanisms of three typical natural organisms, Namib Desert beetles, spider silk, and cactus, along with their bionic surfaces for fog collection devices, are discussed. Additionally, other biological surfaces exhibiting fog transport properties are presented. The main challenges regarding the fabrication and application of bionic fog collection are summarized. Furthermore, we firmly believe that environmentally friendly, low-cost, and stable fog collection materials or devices hold promising prospects for future applications.
摘要：
水资源短缺已经成为一个严重的全球威胁，特别是在干旱和欠发达地区。然而,在这些干旱条件下，某些昆虫和植物已经进化出从雾中获取水的能力。仿生雾收集，以被动收获为特征，最低的能源需求，和低维护成本，已被证明是一种有效的集水方法，提供可持续的水源。这篇综述介绍了两种超润湿表面，即,超亲水和超疏水表面，详细介绍了它们的制备方法和在雾采集中的应用。三种典型的自然生物的雾收集机制，纳米布沙漠甲虫，蜘蛛丝,和仙人掌,以及它们用于雾收集装置的仿生表面，正在讨论。此外,提出了其他具有雾传输特性的生物表面。总结了仿生雾收集的制造和应用面临的主要挑战。此外，我们坚信环保，低成本,稳定的雾收集材料或装置具有广阔的应用前景。
