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-dihydroxy styrene, 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: 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: Poly[(3,4-dihydroxymandelic acid)-co-(lactic acid)] can be produced from renewable feedstocks, possesses tunable degradation, and can achieve adhesion strengths rivaling the performance of existing glues and adhesives. In one aspect, a polymer is presented. The polymer includes poly[(3,4-dihydroxymandelic acid)-co-(lactic acid)]. The polymer can be an adhesive. The adhesive is configured to have tunable degradation. The polymer is derived from renewable resources. The renewable resources can include any one of or a combination of starch, cellulose, hemicellulose, lignin, chitin, polyphenols, poly (isoprene), suberin, polyterpenes, polyterpenoids, polyhydroxyalkanoates, rosin-based polymers, triglyceride-based polymers, alginates, and/or proteins.
