This plastic could make paint scratches a thing of the past
Self-healing plastics are nothing new. In fact, IBM stumbled across the discovery of one such polymer by accident not too long ago. But now there's a new Wolverine-like plastic stealing the headlines (okay, fine... 'science journal' headlines) and this time it hails from researchers at the University of Reading in the UK. The supramolecular polyurethane, developed with funding from the Engineering and Physical Sciences Research Council, reportedly repairs itself at body temperature (98.6 degrees F or 37 degrees C). The new material's unique properties allow it to "[flow] like a liquid" when its bonds are disrupted and reform, as its viscosity is lowered when damaged.
