A patented self-cleaning fabric is undergoing a pilot trial at an Israeli factory. According to the website from the Laboratory of Polymer & Composite Materials, the laboratory "develops superhydrophobic interfaces, based on polymer materials. Superhydrophobic interfaces prevent water droplets clustering and allow self-cleaning effect desirable for several applications, including anti-icing systems, agriculture films (anti-fog films), optical windows, coatings for automobile and civil engineering industries. The laboratory of polymer and composite materials developed the unique approach to formation superhydrophobic interfaces based on so-called 'artificial lotus effect'. Our approach allows formation of highly-developed nanostructured reliefs. "The surfaces developed by our laboratory are characterized with extremely high apparent contact angle as high as 165-175 degrees. The technology developed by the laboratory allows production of the metallic superhydrophobic materials as well. The technology is inexpensive and allows manufacturing large area surfaces. Our recent development allows formation of superhydrophobic interfaces based on recycled rubber particles, yielding distinct ecological effect."
The fabric is based on how pigeon feathers shed water.Edit Summary
