Thiol adhesive
WebThis paper reports the synthesis of catechol-functionalized thiol–ene polymer networks as photocurable adhesives, where the adhesive interactions are derived from 4-allylpyrocatechol – a monofunctional alkene readily obtained from natural products of Syzygium aromaticum flower buds (clove). The thiol–ene photopolymerization process … WebJul 31, 2011 · A second mussel protein is now shown to regulate the redox state of these adhesive groups by coupling thiol oxidation to dopa reduction. Mussel adhesion is mediated by foot proteins (mfps) rich in ...
