Bioinspired chemical design to control interfacial wet adhesion

Amazing wet adhesion phenomena in nature have greatly promoted the development of high-performance adhesive materials from fundamental research to practical applications. During the past decades, starting from the phenomenon that marine organisms firmly attach to seaside reefs, considerable efforts have been devoted to the elaborate design of bioinspired high-strength wet adhesives. This perspective focuses on the bioinspired research principle of wet adhesion from marine adhesion phenomena to artificial adhesive molecular engineering, deepened understanding of natural wet interfacial adhesion mechanisms with the innovation of advanced characterization techniques, and the chemical design of wet adhesives evolved from interest traction into application guidance. In addition, this perspective offers insights into the challenges and opportunities in advancing the development of functional wet adhesives.
