ABSTRACT
This work presents a solvent-free recycling method for epoxy-based vitrimers using cystamine as a reactant and depolymerizing agent. The process depolymerizes the vitrimer network via disulfide exchange, enabling the recovery of amine-terminated oligomers that can be re-crosslinked. Applied to carbon-fiber composites, it offers a scalable, sustainable closed-loop recycling solution.
