It Heals and Grows Together

Polymer with amazing self-healing properties.
Sooner or later, a cut to the skin or a broken bone will heal on its own; however, a scratch to a car’s paint or a tear in the wing of an airplane will not. Materials with self-healing properties could help extend the durability of products and make repairs easier. Krzysztof Matyjaszewski and his co-workers at Carnegie Mellon University (Pittsburgh, USA) and Kyushu University (Japan) have now developed a polymer that can repair itself when irradiated with UV light—over and over again. As the scientists report in the journal Angewandte Chemie, this is the first material in which capped covalent bonds repeatedly reattach, even allowing fully separated pieces to be fused back together.
