Abstract: The invention relates to biomimetic adhesive compositions emulating mussel adhesive proteins, wherein multiple chains of a copolymer are interlinked via specific hydrogen bonds and/or ligand-metal-ligand bonds, which serve as sacrificial breakable bonds upon mechanical stress and thereby effectively dissipate the mechanical energy. Accordingly, toughened adhesive compositions with improved ductility and strength may be obtained.

Abstract: The present disclosure relates to adhesive compositions made from the reaction product of plant protein and phenolics, and method of making and using the adhesive compositions. A maximum bonding strength of 7.8±1.5 MPa was obtained using only 1 weight % tannic acid in a zein matrix of pH=7 and cured in 120° C.

Abstract: Embodiments of this invention relate to adhesives, and more particularly to biomimetic heteropolymer adhesive compositions. Certain embodiments relate to biomimetic terpolymer adhesive compositions including dopamine methacrylamide, 3,4-dihydroxyphenylalanine, or 3,4-dihydroxystyrene, mimicking moieties found in marine mussel adhesive proteins. In some embodiments, elastic moduli of the adhesives are preferably selected to match the elastic moduli of the substrates to minimize stress concentrations, to increase the ductility of the adhesive-substrate system, or both.

Abstract: Provided are adhesive compositions comprising copolymers having biomimetic cross-linkable monomers derived from mussel adhesive proteins. Also provided are methods of curing the adhesive compositions, methods of manufacturing the adhesive compositions, and devices comprising the adhesive compositions.
