Covalent adaptable networks derived from itaconic acid-based epoxy and sulfur: Facile synthesis and applications in adhesives and carbon fiber composites
Design of covalent adaptable networks (CANs) that avoid high costs and complex preparation procedures is critical for sustainable development. Herein, a recyclable and degradable epoxy-sulfur CAN (ExSy) was prepared by mixing bio-based epoxy and sulfur under solvent- and catalyst-free conditions. The epoxy was derived from the abundant and inexpensive bio-resource itaconic acid, and sulfur is a naturally occurring and abundant by-product of oil and gas desulfurization. The resulting ExSy exhibits surprisingly tunable properties, including excellent tensile strength (∼65 MPa) and creep resistance, surpassing those of previously reported CANs prepared via inverse vulcanization. Furthermore, ExSy has potential applications in the adhesive and carbon fiber composite fields, enabling reclamation of carbon fibers. This work presents a sustainable and cost-effective strategy for developing high-performance CANs using bio-based and industrial by-product feedstocks, and the reuse of carbon fibers contributes to circular economy principles, reducing waste and resource consumption in material applications.
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
