摘　　要：静电纺纳米纤维膜具有纤维直径小、比表面积大、孔隙率高等优势,使其在空气过滤领域具有广阔的应用前景。相比特殊结构的纳米纤维膜,常规的静电纺纤维膜堆积密度大、过滤阻力高,增加了在实际使用中的能源消耗。从静电纺纤维膜结构和过滤性能的角度探讨了高效低阻空气过滤纳米纤维膜的构筑,介绍了珠粒、突起和多孔结构纤维膜在空气过滤领域的研究进展,指出了多级结构静电纺纳米纤维膜是高效低阻空气过滤膜的重点研究方向。Electrospun nanofiber membrane has the advantages of small fiber diameter, large specific surface area and high porosity, which makes it have a broad application prospect in the field of air filtration.Compared with the nano-fiber membrane with special structure, the conventional electrostatic fiber membrane has high packing density and high filtration resistance, which increases the energy consumption in practical use. From the point of view of the structure and filtration performance of electrospun fiber membrane, the construction of high efficiency and low resistance air filtration nanofiber membrane are discussed, and the research progress of beads, protuberance and porous structure fiber membrane in air filtration field is introduced. It is pointed out that the multistage electrospun nanofiber membrane is the key research direction of high efficiency and low resistance air filter membrane.
