SciDevNet: A novel and affordable fabric may improve the efficiency of water collection from fog, helping to provide freshwater in desert areas.
Researchers from the Eindhoven University of Technology (EUT), in the Netherlands, and Hong Kong Polytechnic University, China, turned a cotton fabric into a water-collecting material by coating it with a polymer called PNIPAAm.
The fabric switches between absorbing moisture directly from the air when it is foggy and cold, and releasing it as water at warmer...
