生物质资源是一种储量丰富的可再生资源。生物质资源的高效利用不仅具有非常巨大的经济和生态价值,而且对新能源与生物基合成材料的可持续发展战略具有重大意义。由植物纤维素等生物质材料经生物或者简单化学过程处理,可获得丰富的生物基单体2,5-呋喃二甲酸(FDCA)。FDCA可用于生物基聚酯材料的合成。FDCA系列聚酯材料性能优异,可作为由石油基单体对苯二甲酸(PTA)而合成的芳香族聚酯材料(例如PET)的一种潜在的高性能生物可降解替代材料。本文简要说明了生物基单体FDCA的物性及制备方法,并重点阐述了包括聚呋喃二甲酸乙二酯(PEF)与聚呋喃二甲酸丁二酯(PBF)等一系列FDCA基聚酯材料的合成及性质,同时对FDCA基聚酯材料的应用进展进行了简要介绍,最后对FDCA基聚酯生物基合成材料的发展前景作了初步展望。
Biomass resources are a rich renewable resource. The efficient use of biomass resources not only has tremendous economic and ecological value, but also has great significance for the sustainable development strategy of new energy and bio-based synthetic materials. From biological materials such as plant cellulose and other biological processes or simple chemical treatment, can be rich in bio-based monomer 2,5-furandicarboxylic acid (FDCA). FDCA can be used in the synthesis of bio-based polyester materials. FDCA series polyester materials perform well as a potentially high performance biodegradable alternative to aromatic polyester materials (such as PET) synthesized from petroleum-based monomer terephthalic acid (PTA). This article briefly described the physical properties and preparation methods of bio-based monomer FDCA, and focused on a series of FDCA-based polyester materials including polyethylene furandicarboxylate (PEF) and polybutylene furandicarboxylate (PBF) Synthesis and properties of FDCA-based polyester composites. At the same time, the application of FDCA-based polyester composites was briefly introduced. Finally, the prospects of the development of FDCA-based polyester bio-based composites were also discussed.
