Abstract

Development of sustainable adhesives requires simultaneous realization of high strength and excellent ductility but remains challenging. Here, we prepare furan-ring-containing biomimetic multiphase polymers to afford fully sustainable, strong, and supertough adhesives, showing that the key factors of these adhesives are the asymmetric structure of the aromatic furan ring and its oxygenated nature. The adhesives exhibit several beneficial structural features: easy phase separation, dynamic hard phases capable of rupturing and re-forming to dissipate energy, strain-induced orientation and recrystallization, and multiple oxygen binding to substrates. All of these factors act in synergy to result in high adhesion strength (12.1 MPa), exceptional toughness (work of debonding >13,000 N m−1), excellent temperature adaptability, and impressive solvent resistance. Thus, the present work provides new perspectives on the design of strong, tough, and fully sustainable adhesives.
