Self-healing plastic repairs itself in 10 seconds even under water

The new plastic is capable of quickly healing under water, even in extreme conditions. It can be used in emergency situations at sea, as it maintains its strength and self-healing.
This material was developed by Lili Chen, Tsinghua University in China, and her coworkers. It is called Rapid Underwater Selfhealing Stiff Elastomer. Chen says that self-healing polymers at room temperature have poor underwater stability, low healing power, and a slow healing rate.

RUSSE is made up of tiny chunks of a soft polymer that's used in paints and connected by nanometre-sized cables
