These 'foldable bottlebrush polymer networks' could pave the way for materials that are both robust and highly flexible.
An artistic rendering of a network formed by crosslinking foldable bottlebrush polymers, which feature a collapsed backbone grafted with many flexible linear side chains.
Researchers at the University of Virginia’s School of Engineering and Applied Science have developed a revolutionary polymer design that challenges a long-standing principle in material science: the trade-off between stiffness and stretchability. “This limitation has held back the development of materials that need to be both stretchable and stiff, forcing engineers to choose one property at the expense of the other,” Huang said. “Imagine, for example, a heart implant that bends and flexes with each heartbeat but still lasts for years.”
