Self-Healing Car Coating Repairs Scratches : Discovery News
University of Mississippi researchers have developed a polyurethane coating that is able to repairs scratches if left in the sun for a few hours. The key is a minuscule amount of chitosan, related to chitin which is found in lobster and crab shells. When the material is scratched, the chitosan reforms its bonds, pulling the polyurethane along. Within an hour the scratch is gone. They are now planning to conduct long-term testing so they can determine if it is commercially viable.
