静电纺丝是一种相对简单的方法，可以从不同聚合物和聚合物共混物的溶液中生产亚微米纤维。静电纺丝纳米纤维未来的广泛应用是过滤。本文研究了静电纺丝纳米纤维的过滤性能。在实验过程中，在纺粘层和熔喷亚层上电纺了不同面积重量的纳米纤维层。通过一系列实验，分别测定了纳米纤维网和亚层的纤维直径、孔径、过滤效率和过滤阻力。结果表明，纳米纤维的纤维直径远小于亚层的纤维直径。研究还发现，纳米纤维网的孔径远小于亚层，纳米纤维网的孔径系数变化也远小于亚层。此外，亚层的过滤效率和过滤阻力低于纳米纤维网。文中还对效率与压降之间的平衡进行了研究。#2006威利期刊，Inc.应用理科杂志102：1285-1290,2006
Electrospinning is a relatively simple method to produce submicron fibers from solutions of dif- ferent polymers and polymer blends. The extensive applica- tion in future of electrospinning nanofibers is filtration. In this article, the filtration properties of electrospinning nano- fibers were investigated. During the experiments, nanofibers layers with different area weight were electrospun on the spunbonded or meltblown sublayers. Fiber diameter, pore diameter, filtration efficiency as well as filtration resistance of nanofibers web and sublayers were measured, respec- tively, through a series of experiments. The results show that the fiber diameter of nanofibers is much smaller than that of sublayers. It is also found that the pore diameter of nanofi- bers web is much smaller than sublayers and coefficient variation of the pore diameter of nanofibers web is much smaller than sublayers. Moreover, the filtration efficiency and filtration resistance of sublayers are lower than nanofi- bers webs. The balance between efficiency and press drop is also investigated in the article. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 1285-1290, 2006
