摘要：

为促进静电纺纳米纤维在空气过滤领域中的应用,开发性能更加优异的新型纳米纤维空气过滤膜,以近年来国内外静电纺丝技术制备多级结构纳米空气过滤材料的相关研究为基础,综述了静电纺制备具有微纳米凸起、纳米蛛网、层层复合、多孔、刺状、树枝状及核壳等结构空气过滤材料的最新研究进展,分析和讨论了多级结构微纳米空气过滤材料的制备方法,指出了现有研究中存在的不足,并对未来的发展方向进行了总结和展望。认为多级结构可有效实现过滤材料高效率、低阻力、高强度、阻燃等的功能化,相较于传统的纳米纤维过滤材料具有更好的应用前景。

Abstract:

This review paper was written to promote applications of electrospun nanofibers in the field of air filtration, and to report development of new nanofiber air filtration membranes with more performance advantages. The latest progress in the preparation of air filtration materials was reviewed in the areas of micro-nano-bulge, nano-spider web, layer-by-layer composite, porous, spiny, tree-like and core-shell structures by electro-spinning. The preparation methods of hierarchical micro-nano air filtration materials were analyzed, discussed and critically commented. While the progress and shortcomings of existing work were pointed out. This paper also proposed future development directions for this research area. The review concludes that the hierarchical structure is effective in functionalizing filtration materials (such as high efficiency, low resistance, high strength, flame retardant, and so on) and has better application prospects than traditional nanofiber filtration materials.

Key words: electro-spinning, hierarchical structure, nanofiber, air filtration material
