Accessing the Next Generation of Synthetic Mussel-Glue Polymers via Mussel-Inspired Polymerization
New Paper released in Angewandte Chemie International Edition.
Abstract: The formation of cysteinyldopa as biogenic connectivity in proteins is used to inspire a chemical pathway toward mussel-adhesive mimics. The mussel-inspired polymerization (MIPoly) exploits the chemically diverse family of bisphenol monomers that is oxidizable with 2-iodoxybenzoic acid to give bisquinones. Those react at room temperature with dithiols in Michael-type polyaddition, leading to polymers with thiol–catechol–connectivities (TCC). A set of TCC-polymers prove adhesive behavior even on challenging poly(propylene) substrates and there they compete in dry adhesive strength with commercial epoxy resins. The MIPoly promises ease of scale up and exhibits high modularity to tailor adhesives, as proven on a small library, where one candidate shows wet adhesion on aluminum substrates in both water and sea water models.
