Solvent‐Exchange‐Assisted Wet Annealing: A New Strategy for Superstrong, Tough, Stretchable, and Anti‐Fatigue Hydrogels

, respectively. These superb mechanical properties compare favorably to those of other tough hydrogels, organogels, and even natural tendons and synthetic rubbers. This work provides a new and effective method to fabricate superstrong, tough, stretchable, and anti-fatigue hydrogels with potential applications in artificial tendons and ligaments.
