Biomimetic strategy leads to strong, recyclable rubber
(PHYSorg.com Chemistry)

Inspired by nature, Chinese scientists have produced a synthetic analogue to vulcanized natural rubber. Their material is just as tough and durable as the original. In the journal Angewandte Chemie, they reveal the secret to their success: short protein chains attached to the side-chains of the polymer backbone ensure stable physical cross-linkage and give the material a `self-reinforcing` effect under strain. In contrast to conventional rubbers, it is much easier to recycle.
