제목 Sustainable Adhesive Thermosets: Preparation, Reuse, and Signal-Induced De-Bonding
초록 In this presentation, we demonstrate sustainable adhesive thermosets synthesized via simple thiol-ene photopolymerization. The adhesives consist of a reversible cross-linker and a self-immolative linker; the former unit contains a triazolium moiety that supports the cross-linked structure yet causes covalent bond exchange via transalkylation, while the latter, phenyl-based unit generates a signal-specific, elimination reaction that promotes selective de-cross-linking of the entire networks. Therefore, the materials showed a high lap-shear strength as found in a commercial glue and could be reused by heat treatment. Furthermore, the de-cross-linking reaction rapidly de-bonded the polymer adhesives after exposure to the molecular signal.
