Herein, a simple but robust hydrogel network formed by copolymerization of divinyl benzene with acrylamide in micellar solutions for ultra\u2010high fracture resistance and self\u2010recoverable stretchability is proposed. The network provides dynamic association of hydrophobic domains and homogeneous crosslinking of hydrophilic chains, which shows step\u2010by\u2010step deformation process. The dynamic associations allow recoverable small deformations, then the homogeneous crosslinking ensures reversible unfolding and alignment of polymer chains to self\u2010strengthen for ultra\u2010large deformations without crack propagations. The resultant hydrogels exhibit comprehensive unbreakable feature with self\u2010recoverable ultra\u2010high stretchability (100% recovery from 10\u202f200% strain), superior fracture resistance (toughness &gt; 26\u00a0kJ m<jats:sup>\u22122<\/jats:sup>), and anticrack propagation and fatigue (fatigue threshold: \u22482.5\u00a0kJ m<jats:sup>\u22122<\/jats:sup>). Even the prenotched hydrogels can undergo tens cyclic loads at 10\u202f200% strain and thousands cyclic loads at 200% strain without noticeable changes in mechanical performance. The robust network prepared from homogeneous hydrophobic crosslinking provides a facile approach and a new mechanism to explore tough hydrogels with superior antifracture and extreme self\u2010recoverable deformability for diverse applications.<\/jats:p>","DOI":"10.1002\/adma.202206904","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T08:51:26Z","timestamp":1661331086000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":108,"title":["Unbreakable
