New Fabric Absorbs 340% of Its Weight in Water from Fog or Mist

Brett Jordan at Flickr /CC BY 3.0 The development of a new inexpensive treatment for cotton fabric could help boost efforts to collect water from fog or mists in desert regions, as it is not only remarkably effective in absorbing water but also releases it just as easily. In extremely arid regions, fog or mist harvesters can be a fairly effective method for collecting water but they generally require a strong air flow to function. This new treated fabric is effective without the need for wind, and can also be used to collect and release water where it is most needed for agricultural purposes -- directly on the ground. © TU Eindhoven/Bart van Overbeeke Researchers at Eindhoven University of Technology (TU/e), working together with researchers at the Hong Kong Polytechnic University (PolyU), found that when a coating of a polymer, PNIPAAm , is applied to cotton fabric, it al...
