Redox-Triggered Debonding of Mussel-Inspired Pressure Sensitive Adhesives: Improving Efficiency Through Functional Design

New paper released in Angewandte Chemie.

Biomimetic mussel-inspired polymers based on thiol-catechol-connectivities are promising candidates for adhesives in a circular economy. However, the amount of simplification of the chemical structure can have an impact on the function of the polymer. Here, debonding by oxidation of TCC-catechols is demonstrated, comparing a fully synthetic monomer with a DOPA-based dipeptide. The dipeptide enhanced the debonding efficiency, combining smart design and natural feedstock – two critical aspects of circularity.
