The multilevel fatigue resistance mechanism of tough and self-healing hydrogels with a hierarchical structure was revealed. We investigate the fatigue resistance of chemically cross-linked polyampholyte hydrogels with a hierarchical structure due to phase separation and find that the details of the...
