Mussel-inspired dynamic poly(disulfides) ultra-strong underwater adhesives

Inspired by mussels' unique underwater adhesion ability, DOPA chemistry, which plays a key role in adhesive proteins, has become a typical supramolecular toolbox for designing water-resistant adhesive materials, resulting in elegant progress based on the scaffold of (hydro)gels. However, very few studies have focused on the DOPA-functionalized solvent-free network, which may enrich the supramolecular binding of DOPA moieties to the surface by avoiding solvation competition, and further boost the material performance of the bio-inspired adhesive material.
