Self-Regenerating Polymer
Posted by Big Gav
Transmaterial has a post on a polymer that can repair itself - Self-Regenerating Polymer.
Researchers at Spain’s Center for Electrochemical Technologies (CIDETEC) have created a polymer capable of self-repairing at room temperature without the need of any catalysts or any external stimulus. After being cut in half, the material is able to regenerate itself in just two hours, fully recovering its mechanical properties.
