Strong, tough, and repeatable adhesion of an alternating peptide comprising phenyl glycine as a repeating unit

Abstract

A new strategy for preparing peptide-based adhesive materials is provided. An exactly alternating peptide with glycine-N-butylphenyl glycine dipeptide repeating units exhibits excellent repeatable adhesion capacity. The adhesive properties are attributed to the viscoelastic properties and microfibril formation, which are tunable by simple manipulation of the reaction component on polymerization.
