通过冷凝空气中的水蒸气进行水收集，有可能缓解全球干旱地区的缺水问题。当水蒸气在冷却的表面冷凝时，微小的水滴起到了热屏障的作用。因此，为了高效地收集水，必须迅速将它们移走。被动的液滴去除技术依赖于密集分布的液滴的现场生长和直接接触。然而，去除导致水收集率较低的亚微米水滴是一项具有挑战性的工作。在这里，我们提出了一种粗化效应，以快速去除直径的水滴
Water harvesting through the condensation of vapor in air has the potential to alleviate water scarcity in arid regions around the globe. When water vapor is condensed on a cooled surface, tiny water droplets act as thermal barriers. Thus, they must be removed rapidly for efficient water harvesting. Passive technologies for droplet removal rely on in-site growth and direct contact of densely distributed droplets. However, it is challenging to remove submicrometer droplets that lead to a poor water harvesting rate. Here, we present a coarsening effect to rapidly remove water droplets with diameters
