## Description

- description: Recycling of epoxy resin and its composites is extremely difficult
    due to its thermoset nature. In this study, we proposed the environmentally-friendly
    recycling system of epoxy resin with dynamic covalent bonding in the assistance
    of cysteine-containing tripeptide, so-called glutathione. The glutathione attached
    on the epoxy resin and resulted in the cleavage of dynamic disulfide bonds of
    epoxy resin through thiol-disulfide exchange reaction between the thiol group
    of glutathione and disulfide bonding of epoxy resin, followed by the scission
    of epoxy networks. Therefore, the degraded epoxy residue was dissolved into chloroform.
    Finally, this resulting product could be reused as reagent for preparation the
    new epoxy materials with approximately 90% of initial mechanical strength via
    regeneration of disulfide bonding through heating. This work demonstrated the
    different aspect to understand the decomposition and recycling of thermosetting
    networks and the wide application under more environmentally friendly condition.
