摘　　要：环氧树脂是目前应用最为广泛的热固性树脂之一,其固化后会形成不溶、不熔的高度交联的三维网络结构,从而导致树脂及其碳纤维复合材料的降解困难而且难以再加工,造成了严重的资源浪费与环境污染。采用可再生生物质原料制备生物基可降解环氧树脂及其碳纤维复合材料,在缓解能源危机、减轻环境污染和实现资源再利用上具有重要意义。综述了生物基可降解环氧树脂及其可回收碳纤维复合材料的研究进展,主要包括含有热或化学不稳定键的可降解环氧树脂的合成、性能、降解机理及其碳纤维的无损回收,并总结了其优缺点。Epoxy resin is one of the most widely used thermoset resins,and it will form an insoluble and non-melting highly cross-linked three-dimensional network structure after curing.Therefore,epoxy resin and its carbon fiber composites are difficult to degrade and reprocess,resulting in serious waste of resources and environmental pollution.The preparation of bio-based degradable epoxy resins and their carbon fiber composites from renewable biomass raw materials is of great significance in alleviating the energy crisis,reducing environmental pollution and realizing resource reuse.The research progress of bio-based degradable epoxy resins and their recyclable carbon fiber composites was reviewed,mainly including the synthesis,properties,degradation mechanism of bio-based degradable epoxy resins containing thermally or chemically unstable bonds,as well as the non-destructive recovery of carbon fibers.Finally,their advantages and disadvantages were summarized.
