Here, we report a dual phase\u2010separated nanodomain strategy that resolves this trade\u2010off by transforming reversible cross\u2010links into spatially confined reinforcing nanodomains. Elastomers are fabricated via copolymerization of rigid aromatic polyurea segments with flexible poly(urethane\u2010urea) chains containing acylsemicarbazide moieties. The resulting elastomers exhibit an exceptional combination of mechanical properties, including tensile strength of 104.6\u00a0MPa, Young's modulus of 43.1\u00a0MPa, toughness of 350\u00a0MJ m\n                    <jats:sup>\u22123<\/jats:sup>\n                    , and full recovery after 600% strain. Small\u2010angle x\u2010ray scattering and electron microscopy reveal two distinct nanodomains originating from self\u2010assembled aromatic polyurea segments and acylsemicarbazide\u2010stacked hydrogen\u2010bond arrays, respectively. Their synergistic reinforcement increases matrix rigidity while preserving entropy elasticity, enabling the simultaneous realization of ultrahigh mechanical robustness and excellent elastic recovery. The elastomers further demonstrate outstanding puncture resistance, environmental stability, healability, and reprocessability. When used as binders for carbon\u2010fiber fabrics, the composites achieve record\u2010high fracture energies of up to 2059\u00a0kJ m\n                    <jats:sup>\u22122<\/jats:sup>\n                    , owing to the exceptional mechanical robustness and energy dissipation of the elastomer, together with strong elastomer\u2010fiber interfacial adhesion. This dual nanodomain design provides a novel route to high\u2010performance elastomers that transcend conventional strength\u2010modulus\u2010elasticity trade\u2010offs.\n                  <\/jats:p>","DOI":"10.1002\/adma.74001","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T06:43:58Z","timestamp":1783925038000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Resolving the Strength\u2013Modulus\u2013Elasticity Tradeoff in Elastomers Using Dual Phase\u2010Separated Nanodomains"],"prefix":"10.1002","volume":"38","author":[{"given":"Xiang","family":"Wei","sequence":"first","affiliation":[{"name":"State Key Laboratory of Supramolecular Structure and Materials College of Chemistry Jilin University  Changchun P.
