A laboratory in Tennessee has developed a polymer that contains extreme elongation and self-healing abilities. The material can stretch from 1,000 to 5,600 percent before breaking. After breaking, the material can be healed by touching the two pieces together, with no loss of mechanical performance. Complete healing occurs in 120 minutes at room temperature, or in 20 minutes at higher temperatures. Healing fully restores the material and lets it go back to doing what it was meant to do. These self-healing, elastic features can lead to longer lasting, better performing products.
