Grafting self-immolative poly(benzyl ether)s toward sustainable adhesive thermosets with reversible bonding and triggered de-bonding capabilities

Abstract

This paper demonstrates a molecular design concept for stimuli-responsive polymer adhesives. Self-immolative poly(benzyl ether) (PBE) is synthesized as a functional macro-monomer that provides multiple reversible cross-linking points and autonomously depolymerizes in response to a specific stimulus. Grafting only 0.1 mol% PBE onto a soft polynorbornene matrix leads to the fabrication of an adhesive thermoset that not only acts as a high-shear pressure-sensitive adhesive but is also reusable and readily removable when no longer required. This concept can be refined and realized by tailoring the composition of the monomer, including other functions, or incorporating a diverse range of polymeric structures to produce sustainable applications for practical use.
