Tough dual nanocomposite hydrogels with inorganic hybrid crosslinking†
Abstract
A dual nanocomposite hydrogel with inorganic hybrid crosslinking was fabricated through a simultaneous sol–gel technique and free radical polymerization. Due to the multi-strengthening mechanism of the dual nanocomposite, the hydrogel was super tough and strong with a compressive stress of 32.00 MPa without rupture even at 100% strain, while it exhibited excellent fatigue resistant properties.
