Super Hygroscopic Polymer Film Can Harvest Water from Arid Air

Atmospheric water harvesting (AWH) technology and design principle of super hygroscopic polymer films (SHPFs): (a) key steps of AWH technology; (b) geographic distribution of world average annual relative humidity; regions with less than 40% relative humidity are indicated from brown to red (warm color) regions; (c) material design of SHPFs for AWH at low relative humidity; (d) qualitative comparison of different materials in terms of core requirements for practical application of AWH.

Researchers at the University of Texas at Austin have developed a low-cost polymer film made of renewable biomass and hygroscopic salt that can extract atmospheric water in arid environments; these materials cost a mere $2 per kilogram, and a single kilogram can produce more than 6 liters of water per day in areas with less than 15% relative humidity and 13 liters in areas with up to 30% relative humidity. Atmospheric water harvesting (AWH) technology...
