摘要：Developing molecular approaches to the creation of robust and water-resistant adhesive materials promotes a fundamental understanding of interfacial adhesion mechanisms as well as future applications of biomedical adhesive materials.Here,we present a simple and robust strategy that combines natural thioctic acid and mussel-inspired iron-catechol complexes to enable ultra-strong adhesive materials that can be used underwater and simultaneously exhibit unprecedentedly high adhesion strength on diverse surfaces.Our experimental results show that the robust crosslinking interaction of the iron-catechol complexes,as well as high-density hydrogen bonding,are responsible for the ultra-high interfacial adhesion strength.The embedding effect of the hydrophobic solvent-free network of poly(disulfides)further enhances the water-resistance.The dynamic covalent poly(disulfides)network also makes the resulting materials re configurable,thus enabling reusability via repeated heating and cooling.This molecule-engineering strategy offers a general and versatile solution to the design and construction of dynamic supramolecular adhesive materials.
