A self-healing raincoat? It sounds like something out of a comic book, a group of Scandinavian researchers working for the EU project [email protected] have been developing a new type of textile coating that automatically seals tears on the surface of waterproof workwear. The goal is to create a new generation of “intelligent” clothing for professional fishermen. Working with the plastic material polyurethane, scientists have added micro-capsules containing a liquid sealant to the coating of the fabric. When the coating tears, the capsules burst and release the sealant, which hardens when it comes in contact with water and air.
