摘要
微纳米纤维由于比表面积高、长径比高和孔隙率高等优点在制备空气净化滤膜方面极具应用潜力,但始终面临高的过滤效率和低过滤阻力之间的矛盾。文中首先介绍了不同材料制备的微纳米纤维膜的过滤性能,并对不同材料的特性和过滤效果进行了分析;其次总结了典型的微纳米纤维膜结构,包括纤维形貌、纤维膜内结构和层间结构;最后对高效低阻微纳米空气滤膜今后的发展方向进行了展望。
Due to the advantages of high specific surface area,high aspect ratio and high porosity,micro-nano fibers have great application potential in the preparation of filtration membranes for air purification,but they always face the contradiction between high filtration efficiency and low filtration resistance.In this paper,the filtration properties of different materials were introduced firstly,and the filtration properties and filtration effects of different materials were analyzed.Secondly,the typical structure of micro-nano fiber membranes was summarized,including the morphology,internal structure and interlayer structure of fiber membranes.Finally,the future development directions of high efficiency and low resistance micro-nano air filters are prospected.
