Abstract: Simultaneously enhancing hydrogels' strength, stretchability, toughness, fatigue resistance, and tunable water content remains a challenge. Here, a universal "pre-freezing-assisted wet-annealing" strategy addresses these issues in poly(vinyl alcohol) (PVA) hydrogels. This dual-phase process enables controlled phase… read more here.
