Abstract People worldwide suffer from poor access to water, with more than 3 billion lacking basic handwashing facilities and more than 2 billion without water services at their homes. This global problem needs new, cost-effective and efficient solutions that can be employed in places with scarce water sources. One potential sustainable solution is fog water collection, inspired by the way nature harvests water from humid air via condensation processes or from fog. Currently, a common medium to collect fog with the highest water collection efficiency is the Raschel mesh. By incorporating electrospun polyvinylidene fluoride (PVDF) fibers we improved water collecting efficiency of commercial Raschel mesh by more than 300%. We show a relatively simple to implement and inexpensive system that builds on top of already applied solutions and expands the capabilities of existing designs.

使用电纺随机排列的聚偏二氟乙烯 (PVDF) 纤维提高集雾器的集水效率

摘要 世界各地的人们难以获得水源，超过 30 亿人缺乏基本的洗手设施，超过 20 亿人的家中没有供水服务。这一全球性问题需要新的、具有成本效益且高效的解决方案，这些解决方案可用于水资源稀缺的地方。一种潜在的可持续解决方案是雾水收集，其灵感来自大自然通过冷凝过程或雾从潮湿空气中收集水的方式。目前，集水效率最高的雾气收集介质是拉舍尔网。通过加入电纺聚偏二氟乙烯 (PVDF) 纤维，我们将商用拉舍尔网的集水效率提高了 300% 以上。
