Team solves a nearly 200-year-old challenge in polymers to offer independent control of stiffness and stretchabilityThis crosslinking process creates a polymer network, transforming the sticky ... for soft robotic systems that need to flex, bend and stretch repeatedly. Stiffness and extensibility—how far ...
A double network hydrogel being stretched to different lengths. The necked region of the hydrogel indicates rupture of the first polymer network (Photo: WPI-ICReDD). New double network hydrogel ...
Take the tangled spaghetti-soup of a polymer melt and stretch it: the immediate response is like that of an elastic network, as the polymers are forced to deform through their mutual entanglements.
