Covalent Adaptable Networks: Reversible Bond Structures Incorporated in Polymer Networks

Smart and responsive: Reversible transesterification reactions were recently used within a polymer network to create a covalently crosslinked material that is capable of being processed as well as mended and recycled. This work is highlighted in the context of the covalent adaptable network approach and illustrates the bond cleavage and reformation mechanism that enable the adaptability of these materials (see picture).
