摘要:

石油资源日渐枯竭、白色污染日趋严重,以木质纤维素资源为原料制备生物基聚呋喃二甲酸乙二醇酯(PEF)已成为生物炼制与绿色化工领域研究的热点之一。与广泛应用的聚对苯二甲酸乙二醇酯(PET)和聚碳酸酯(PC)等石油基塑料相比,PEF不仅具有优异的热性能和机械强度,而且在气体阻隔性能上的优势更为明显,被认为是PET的完美替代品。然而,PEF存在断裂伸长率过低、产品颜色深、难以降解、深结晶速度慢等问题,因此,在实际应用中需要对其进行改性。本文重点综述了PEF改性研究的进展,包括共聚、共混等多种改性方法;总结了催化剂类型、不同二醇或二酸改性单体、反应进行方式以及添加剂等对PEF性能影响的规律,并展望了改性PEF的发展趋势和应用前景。

Abstract:

With the depletion of petroleum resources and the increasingly serious white pollution, the preparation of bio-based poly(ethylene 2, 5-furandicarboxylate)(PEF) from lignocellulosic resources has become one of the research hotspots in the fields of biorefinery and green chemical industry. Compared with petroleum-based plastics, such as poly(ethylene terephthalate)(PET) and polycarbonate(PC), PEF not only has excellent thermal properties and mechanical strength, but also has more obvious advantages in gas barrier properties, which is considered as a perfect substitute for PET. However, PEF also has some drawbacks, including low elongation at break, dark color, difficult degradation and slow deep crystallization speed. Therefore, it is necessary to modify PEF before practical application. In this paper, the research progresses of PEF modification, including copolymerization, blending and other modification methods were reviewed. The effects of different diols or diacid modified monomers, catalyst types, reaction modes, additives on the properties of PEF were summarized, and the developing trend and application prospects of modified PEF were discussed.

Key words: furandicarboxylic acid, poly(ethylene furandicarboxylate), copolymerization modification, blending modification
