Stretch test (VIDEO)

ire wear and tear is a major source of microplastic pollution. Scientists at Duke and MIT say advances in polymer design could help tackle this problem. In new research, they describe a way to make more durable rubbery materials that can take a beating and still bounce back. Watch as they put two materials to the test. Both samples are 98% acrylate, and stretchy like a rubber band. But the left one is 9 times tougher without losing elasticity. The secret to its toughness lies in weak bonds that actually make it stronger.
