Mussel-mimetic strong adhesive resin from bio-base polycoumarates

Abstract

We have synthesized novel Mussel-mimetic adhesive resin from biomass monomers. Because the adhesive resin contains catechol groups at its chain ends, which is similar to the chemical structure of 3,4-dihydroxyphenyl-L-alanine, produced by Mussel, it demonstrates strong adhesive characteristics onto organic and/or inorganic surfaces beyond those of the conventional instant superglue. The origin of this strong adhesive characteristic was attributed to strong hydrogen bond interaction between our new resins and oxidized and/or OH groups on the substrates. © The Society of Polymer Science, Japan (SPSJ) All rights reserved.
