Hard domains formed by hydrogen\u2010bonded urethane linkages provide mechanical strength but limit the chain mobility needed for healing, while soft domains enable elasticity but are more vulnerable to damage. We propose a soft\u2010segment modification strategy that incorporates \u03b1,\u03c9\u2010hydroxyl end\u2010functionalized polyacrylates into conventional TPU structures. Unlike our previous systems based on linear\u2010alkyl acrylates (i.e.,\n                    <jats:italic>n<\/jats:italic>\n                    \u2010butyl acrylate), introducing branched\u2010alkyl acrylic soft segments (i.e., 2\u2010ethylhexyl acrylate) generate side\u2010chain architectures whose segmental dynamics respond more sensitively to temperature. This enhanced thermal responsiveness promotes thermally activated chain mobility and more uniform stress distribution, all without compromising the mechanical contribution of the hard domains. As a result, the acrylic TPUs display high toughness (186 MJ\u00b7m\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>3<\/jats:sup>\n                    ), stable notch performance (fracture energy &gt;197 kJ\u00b7m\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>2<\/jats:sup>\n                    at elongations above 900%), and practical self\u2010healing (\u223c90% recovery at 45\u00b0C within 3\u00a0h). These findings highlight that branched polyacrylate\u2013based soft\u2010segment engineering offers a balanced pathway to mechanically robust and adaptable TPU elastomers.\n                  <\/jats:p>","DOI":"10.1002\/anie.8983737","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T06:41:58Z","timestamp":1770964918000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Highly Tough, Notch\u2010Insensitive, and Fast Self\u2010Healing Thermoplastic Polyurethane Elastomers by Tailored Soft Segment Design"],"prefix":"10.1002","volume":"65","author":[{"given":"Changhoon","family":"Yu","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongdeok","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Sungkyunkwan University  Suwon Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinho","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sunwu","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3673-8069","authenticated-orcid":false,"given":"Joonmyung","family":"Choi","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Sungkyunkwan University  Suwon Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1485-7588","authenticated-orcid":false,"given":"Min Sang","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Polyurethane Elastomers","author":"Hepburn C.","year":"2012"},{"key":"e_1_2_8_3_1","first-page":"114453","article-title":"Polyurethane Types, Synthesis, and Applications\u2014a Review","volume":"6","author":"Akindoyo J.
