“…The results in the Fig. S4(a)† show that an increase in lignin content in the material increases the strength of the material (A, 30 B, 31 C, 32 D 33 and E 34 ) and correspondingly decreases the strain. Compared to lignin-based vitrimers synthesized with other chemical systems, this study exhibits a pronounced advantage in stain.…”

Vitrimers, as dynamic covalent network polymers, represent a groundbreaking advancement in materials science. They excel in their applications, such as advanced thermal-conductivity composite materials, providing a sustainable alternative to traditional polymers. The incorporation of vitrimers into composite fillers enhances alignment and heat passway broadly, resulting in superior thermal conductivity compared to conventional thermosetting polymers. Their dynamic exchange reactions enable straightforward reprocessing, fostering the easy reuse of damaged composite materials and opening possibilities for recycling both matrix and filler components. We review an overview of the present advancements in utilizing vitrimers for highly thermally conductive composite materials.

Dynamic covalent chemistry (DCC) has revolutionized the field of polymer science by offering new opportunities for the synthesis, processability, and recyclability of polymers as well as in the development of new materials with interesting properties such as vitrimers and covalent organic frameworks (COFs). Many DCC linkages have been explored for this purpose, but recently, enamine‐ones have proven to be promising dynamic linkages because of their facile reversible transamination reactions under thermodynamic control. Their high stability, stimuli‐responsive properties, and tunable kinetics make them promising dynamic cross‐linkers in network polymers. Given the rapid developments in the field in recent years, this review provides a critical and up‐to‐date overview of recent developments in enamine‐one chemistry, including factors that control their dynamics. The focus of the review will be on the utility of enamine‐ones in designing a variety of processable and self‐healable polymers with important applications in vitrimers and recyclable closed‐loop polymers. The use of enamine‐one linkages in crystalline polymers, known as COFs and their applications are also summarized. Finally, we provide an outlook for future developments in this field.

Preparation of lignin-based vinylogous urethane vitrimer materials and their potential use as on-demand removable adhesives

Abstract: Conventional thermosets rely on petrochemical products, and cannot be reprocessed, recycled, or reshaped under mild conditions owing to their permanent, highly crosslinked structure. Although some of these materials are down-cycled...
