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.
