中文摘要:

      随着工业进步和社会发展, 水污染已成为全球的主要威胁, 不止影响生态环境, 还会通过食物链累积效应威胁食品质量安全。金属有机骨架(metal-organic frameworks, MOFs)材料是一种多孔晶体材料, 具有多孔性、大比表面积等优势。近几年, 通过静电纺丝技术将MOFs负载到高孔隙率、高柔韧性的纳米纤维(nanofibers, NFMs)上, 有望克服MOFs材料不易循环利用的缺点, 同时这一新兴材料合成技术在水质净化领域的研究尚处于起步阶段, 但是其发展潜力已引起众多学者关注。本文综述了金属有机框架纳米纤维膜合成方法、膜性能参数及其在水质净化方面的初步应用, 并对该复合材料未来发展趋势进行展望, 以期为该复合材料进一步的研究发展提供参考。

英文摘要:

      With industrial progress and social development, water pollution has become a major global threat, not only affecting the ecological environment, but also through the cumulative effect of the food chain, thereby threatening food quality and safety. Metal-organic framework (MOFs) materials are a kind of porous crystalline materials, which have the advantages of porosity and large specific surface area. In recent years, loading MOFs onto nanofibers (NFMs) with high porosity and high flexibility and toughness through electrospinning technology is expected to overcome the disadvantage that MOFs materials are not easy to recycle, and at the same time, the research of this emerging material synthesis technology in the field of water purification is still in its infancy, but its development potential has attracted the attention of many scholars. This paper reviewed the synthesis methods, membrane performance parameters and its preliminary application in water purification of metal organic framework nanofiber membrane, and prospected the future development trend of the composite, in order to provide reference for the further research and development of the composite.
