Epoxy vitrimers based on transesterification reactions (TERs) are a type of recyclable thermosets that have been successfully developed in recent years. However, the good thermal performance and the fast network rearrangements are somehow contradicting and difficult to achieve simultaneously in TER-based epoxy vitrimers. This contradiction was solved in this work by a green and simple but effective strategy in which natural glycyrrhizic acid (GL) was associated with sebacic acid (SA) as a hardener to produce epoxy vitrimers based on TERs with different monomer compositions (V1 to V5. ) to manufacture). Thanks to the unique structure of GL, the glass transition temperatures (TG) of vitrimers increased from 31 to 89 ° C, and their stress relaxation time decreased from 390 to 130 s at 180 ° C as the GL content increased. In particular, the Vitrimer V4 showed good thermal stability (decomposition temperature Td5 of 263 ° C), rapid stress relaxation (relaxation time of 130 s at 180 ° C), low malleability temperature (Tshopping mall 116 ° C) and usable us TG (61 ° C). In addition, this vitrimer could be welded, reconditioned, repaired, recycled and chemically degraded at a relatively mild temperature (130 ° C). This work provides a green strategy for vitrimer design that could be useful in the future for the production of recyclable thermosets with high overall performance.
