Engineering of Chain Rigidity and Hydrogen Bond Cross‐Linking toward Ultra‐Strong, Healable, Recyclable, and Water‐Resistant Elastomers
Jilin University · State Key Laboratory of Supramolecular Structure and Materials
Abstract
Abstract High‐performance elastomers have gained significant interest because of their wide applications in industry and our daily life. However, it remains a great challenge to fabricate elastomers simultaneously integrating ultra‐high mechanical strength, toughness, and excellent healing and recycling capacities. In this study, ultra‐strong, healable, and recyclable elastomers are fabricated by dynamically cross‐linking copolymers composed of rigid polyimide (PI) segments and soft poly(urea–urethane) (PUU) segments with hydrogen bonds. The elastomers, which are denoted as PIPUU, have a record‐high tensile strength of ≈142 MPa and an extremely high toughness of ≈527 MJ m −3 . The structure of the PIPUU…
