摘　　要：介绍了来源于生物质的环氧类玻璃的分类和制备,综述了近年来基于可逆共价键的生物基环氧类玻璃材料的研究进展,该材料结合了热固性塑料优异的力学性能和热塑性塑料的可再加工性,且可交换的网络赋予玻璃体优异的再加工、自修复以及可回收性能,有望取代传统热固性塑料在航空航天材料、电子器件、日常生活消费品等领域得到广泛应用.The classification and preparation of epoxy vitrimers from biomass were introduced,and the research progress of bio-based epoxy vitrimers based on reversible covalent bonds in recent years was reviewed. The material combines the excellent mechanical properties of thermosetting plastics and the reworkability of thermoplastics,and the exchangeable network endows the vitrimers with excellent reprocessing,self-healing and recyclability properties,which is expected to replace traditional thermosetting plastics and be widely used in aerospace materials,electronic devices,daily consumer goods and other fields.
