Thanks to their high functionality in aliphatic and phenolic OH groups, lignins have long been studied as precursors for crosslinked polymer materials, i.e. thermosets. A major drawback of this material family is its limited circularity. Indeed, crosslinked polymers cannot melt, precluding mechanical recycling.An attractive strategy to overcome this limitation while maintaining high mechanical performance is to introduce dynamic linkages into the polymer networks. Upon heating, the dynamic bonds can rearrange within the networks, allowing easy thermal reprocessing. These dynamic networks, called Covalent Adaptable Networks (CAN), have seen tremendous developments in the past years, especially those based on associative bond exchanges, known as vitrimers. The application of this concept to biobased and aromatic feedstocks such as lignins shows great promise for the elaboration of circular biobased materials [1,2]. Recently, our group focused on the development of vitrimers from different lignin feedstocks. We reported several strategies to elaborate vitrimers containing dynamic ester [3,4] or vinylogous urethane bonds [5,6] from chemically modified lignins. We also introduced phenol-yne dynamic bonds as a new pathway towards lignin-based vitrimers, with the great advantage that chemical modification of lignin is not required to synthesize the materials [7]. The materials can be successfully reprocessed several times, and different strategies for their chemical recycling have also been studied. This presentation will give an overview of these recent advances towards the closed-loop recycling of lignin-based materials.
