摘要

A team led by Christoph Weder, a materials scientist at the University of Fribourg in Switzerland, has developed a type of rubbery plastic that "self heals" when exposed to ultraviolet light. The material might one day be incorporated into varnish, paint or mobile phone covers."Just try to imagine how the lifetime of many items could be prolonged if damage could be fixed so easily," said Weder.
