In article number 1705145, Sung Yeon Hwang, Dongyeop X. Oh, Jeyoung Park, and co-workers fabricate remarkably tough room-temperature self-healable thermoplastic polyurethane elastomers. Hard segments with an asymmetric alicyclic structure provide the optimal metathesis efficiency for embedded aromatic disulfide while preserving remarkable mechanical properties. The toughness value of 26.9 MJ m−3 is twice best a previously reported material.
