Vitrimer materials based on the commonly used thermosets can not only exhibit excellent mechanical property and solvent resistance, but also can be flowable and re-processable like thermoplastics, which will provide an effective way for the recycle of cross-linked polymers from the source. The research on vitrimer has been growing fast in recent years, especially epoxy resin vitrimer is mostly and widely investigated. This paper focuses on introducting the design concept and characteristics of epoxy vitrimer, systematically summarizing and analyzing the typical research at present stage, elucidating the direction and challenge for epoxy vitrimer, and providing references for the development of high performance recyclable resins. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1 -->
