Sung Yeon Hwang, Dongyeop X. Oh, Jeyoung Park, and co-workers of Research Center for Bio-Based Chemistry and Korea Research Institute of Chemical Technology (KRICT) fabricate remarkably tough and room-temperature self-healable thermoplastic polyurethane elastomers. Hard segments with an asymmetric alicyclic structure provide the optimal metathesis efficiency for the embedded aromatic disulfide while preserving the remarkable mechanical properties. The toughness value of 26.9 MJ m−3 is twice the best value for a previously reported material.
