An international team of researchers in (China, Germany) has synthesized a new type of temperature-resistant crown-ether-protein (CEP) adhesive by harnessing synergistic host–guest molecular interactions between engineered crown ether and protein building blocks. The resulting adhesive demonstrated ultrahigh shearing adhesion strength of ≈22 MPa over a wide temperature range from −196 to 200 °C, superior to other established supramolecular or polymeric adhesives. The temperature-induced phase transition and internal bound water stabilized the system and led to superb adhesion under extreme conditions. The work offers a promising molecular engineering strategy to fabricate robust supramolecular adhesives for applications under extreme conditions…read more. TECHNICAL ARTICLEÂ
