摘要
热固性树脂广泛用于碳纤维增强树脂基复合材料(carbon fiber-reinforced polymers,CFRPs)的构建,其固化后具有不溶、不熔的特点,导致热固性树脂和碳纤维难以实现回收和再利用。类玻璃高分子材料(vitrimer)兼具热固性树脂与热塑性树脂的优点,可实现高性能CFRPs制备和CFs无损回收。此外,利用资源丰富、廉价易得的木质素及香草醛等生物基原料构建vitrimer及其CFRPs,符合绿色可持续发展理念。本文总结了木质素和香草醛构建生物基vitrimer的方法、性能及其应用;综述了香草醛基vitrimer在可回收CFRPs领域的应用;对木质素/香草醛基vitrimer及其CFRPs的发展方向进行了展望,以期为高性能木质素及其衍生物基vitrimer和CFRPs构建提供借鉴。
Thermosetting resins are widely used in the composition of carbon fiber-reinforced polymers(CFRPs),which are insoluble and non-melting after curing,making thermosetting resins and carbon fibers(CFs)difficult to recycle and reuse.Vitrimer has the advantages of thermosetting and thermoplastic resins,which can achieve high-performance CFRPs preparation and non-destructive recovery of CFs.Moreover,the construction of vitrimer and its CFRPs by the bio-based materials,such as lignin and vanillin,is in line with the green development concept.The methods,properties,and their applications for the preparation of bio-based vitrimer from lignin and vanillin were summarized in this paper;the applications of vanillin-based vitrimer in the recyclable CFRPs were reviewed;the future development of lignin/vanillin-based vitrimer and its CFRPs were outlooked.This paper would provide a reference for the construction of highperformance lignin and its derivative vitrimer and CFRPs.
