摘要

本研究提出了一种以半胺为反应物和解聚剂的环氧基玻璃体无溶剂回收方法。该工艺通过二硫交换使vitrimer网络解聚，使可以重新交联的氨基端低聚物得以恢复。应用于碳纤维复合材料，它提供了一个可扩展的、可持续的闭环回收解决方案。

Closed-loop recycling of bio-based disulfide vitrimer via a solvent-and waste-free strategy†

This work presents a solvent-free recycling method for epoxy-based vitrimers using cystamine as a reactant and depolymerizing agent. The process depolymerizes the vitrimer network via disulfide exchange, enabling the recovery of amine-terminated oligomers that can be re-crosslinked. Applied to carbon-fiber composites, it offers a scalable, sustainable closed-loop recycling solution.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
