Atmospheric water harvesting (AWH) is an emerging approach to solve the worldwide water crisis. Metal-organic frameworks and hydrogels have been extensively explored as sorbents for AWH; however, they suffer from relatively low water sorption capacity in arid conditions, a feature innately owned by a common material: deliquescent sorbents. Deliquescent sorbents are, however, limited by inevitable water leakage and restricted capacity. Here, we develop an efficient AWH approach that achieves an excellent water harvesting capacity of 2.62 g/g even in arid conditions by designing devices consisting of a superhydrophilic inside matrix loaded with deliquescent sorbents for efficient water adsorption, superhydrophobic and elastic fibrous skin for adaptative expansion, and water leakage prevention. The fibrous skin also exhibits a preferred radiative cooling effect, extending effective humidity and sorption capacity. The all-in-one design that combines heterogeneous wettability, radiative cooling, and elasticity-induced adaptivity opens a new route for addressing water challenges in a wide range of working conditions.

大气集水（AWH）是解决全球水资源危机的新兴方法。金属有机框架和水凝胶已被广泛用作 AWH 的吸附剂。然而，它们在干旱条件下的吸水能力相对较低，这是一种常见材料固有的特性：潮解吸附剂。然而，潮解性吸附剂受到不可避免的水泄漏和容量受限的限制。在这里，我们开发了一种高效的 AWH 方法，即使在干旱条件下也能实现 2.62 g/g 的出色集水能力，方法是设计由超亲水内部基质组成的装置，该基质装载有用于高效吸水的潮解性吸附剂，超疏水和弹性纤维皮肤用于适应性扩张，并防止漏水。纤维皮肤还表现出优选的辐射冷却效果，扩展了有效的湿度和吸附能力。结合了异质润湿性、辐射冷却和弹性诱导适应性的一体化设计为解决各种工作条件下的水挑战开辟了一条新途径。
