摘　　要：与石油基聚酯——聚(对苯二甲酸乙二醇酯)(PET)相比,生物基聚酯——聚(2,5-呋喃二甲酸乙二醇酯)(PEF)具有更优异的物理-力学性能,在高阻隔性包装材料、高性能纤维和工程塑料等领域具有广阔的应用前景。然而,PEF及其关键单体的合成技术仍存在很大的挑战,尚未实现工业化;同时,PEF结构-性能的研究也表明其性能上存在一些缺陷,需要进行改性,以促进PEF的加工和应用。本文中,笔者总结近年来PEF的合成技术、结构性能和改性研究的进展,并展望PEF基聚酯新材料的发展趋势和前景。In comparison with petroleum-based polyester poly(ethylene terephthalate)(PET),bio-based polyester poly(ethylene 2,5-furandicarboxylate)(PEF) possesses superior physical-mechanical properties and therefore brighter prospect of applications in high gas barrier packaging materials,high performance fibers,engineering plastics,etc.However,PEF has not been commercialized yet because of great challenges in the synthetic technologies of PEF and its key monomer,2,5-furandicarboxylic acid.At the same time,with the deepening researches on the structure-property relationship of PEF,it is found that there are some inherent shortcomings in PEF property;therefore,modification of PEF is necessary to promote its processing and applications.We review the recent progress in the synthesis,structure-property and modification of PEF,and the developing trend and prospects of PEF-based materials have been discussed.
