With the explosive growth of the world’s population and the rapid increase in industrial water consumption, the world’s water supply has fallen into crisis. The shortage of fresh water resources has become a global problem, especially in arid regions. In nature, many organisms can collect water from foggy water under harsh conditions, which provides us with inspiration for the development of new functional fog harvesting materials. A large number of bionic special wettable synthetic surfaces are synthesized for water mist collection. In this review, we introduce some water collection phenomena in nature, outline the basic theories of biological water harvesting, and summarize six mechanisms of biological water collection: increased surface wettability, increased water transmission area, long-distance water delivery, water accumulation and storage, condensation promotion, and gravity-driven. Then, the water collection mechanisms of three typical organisms and their synthesis are discussed. And their function, water collection efficiency, new developments in their biomimetic materials are narrated, which are cactus, spider and desert beetles. The study of multiple bionics was inspired by the discovery of Nepenthes’ moist and smooth peristome. The excellent characteristics of a variety of biological water collection structures, combined with each other, are far superior to other single synthetic surfaces. Furthermore, the main problems in the preparation and application of biomimetic fog harvesting materials and the future development trend of materials fog harvesting are prospected.

随着世界人口的爆炸式增长和工业用水量的快速增长，世界供水已陷入危机。淡水资源短缺已成为全球性问题，特别是在干旱地区。在自然界中，许多生物可以在恶劣的条件下从雾水中收集水分，这为我们开发新型功能性集雾材料提供了灵感。合成大量仿生特殊可湿性合成表面用于水雾收集。在这篇综述中，我们介绍了自然界中的一些集水现象，概述了生物集水的基本理论，并总结了生物集水的六种机制：增加表面润湿性、增加输水面积、远距离输水、蓄水和蓄水。 , 凝结促进，重力驱动。然后，讨论了三种典型生物的集水机制及其合成。并叙述了它们的功能、集水效率、仿生材料的新发展，它们是仙人掌、蜘蛛和沙漠甲虫。多重仿生学研究的灵感来自猪笼草湿润光滑的唇的发现。多种生物集水结构的优良特性，相互结合，远远优于其他单一的合成表面。进一步展望了仿生集雾材料制备和应用中存在的主要问题，展望了材料集雾材料的未来发展趋势。讨论了三种典型生物的集水机制及其合成。并叙述了它们的功能、集水效率、仿生材料的新发展，它们是仙人掌、蜘蛛和沙漠甲虫。多重仿生学研究的灵感来自猪笼草湿润光滑的唇的发现。多种生物集水结构的优良特性，相互结合，远远优于其他单一的合成表面。进一步展望了仿生集雾材料制备和应用中存在的主要问题，展望了材料集雾材料的未来发展趋势。讨论了三种典型生物的集水机制及其合成。并叙述了它们的功能、集水效率、仿生材料的新发展，它们是仙人掌、蜘蛛和沙漠甲虫。多重仿生学研究的灵感来自猪笼草湿润光滑的唇的发现。多种生物集水结构的优良特性，相互结合，远远优于其他单一的合成表面。进一步展望了仿生集雾材料制备和应用中存在的主要问题，展望了材料集雾材料的未来发展趋势。蜘蛛和沙漠甲虫。多重仿生学研究的灵感来自猪笼草湿润光滑的唇的发现。多种生物集水结构的优良特性，相互结合，远远优于其他单一的合成表面。进一步展望了仿生集雾材料制备和应用中存在的主要问题，展望了材料集雾材料的未来发展趋势。蜘蛛和沙漠甲虫。多重仿生学研究的灵感来自猪笼草湿润光滑的唇的发现。多种生物集水结构的优良特性，相互结合，远远优于其他单一的合成表面。进一步展望了仿生集雾材料制备和应用中存在的主要问题，展望了材料集雾材料的未来发展趋势。
