通过静电纺丝制备了具有各种形态结构（纳米纤维、珠状纳米纤维和复合颗粒/纳米纤维）的聚合物纳米纤维垫，用于气溶胶颗粒过滤。这些聚合物纳米纤维垫的过滤性能是根据测量 20 至 300 nm 的氯化钠 (NaCl) 气溶胶颗粒穿过过滤器时产生的质量因数进行评估的。这些过滤测试结果表明，珠状纳米纤维过滤垫的品质因数是最好的，尽管它们的气溶胶颗粒渗透率是形态结构中最高的。本研究结果表明，聚合物纳米纤维的形貌优化是提高过滤性能的有效方法，必将成为未来新型过滤介质的发展方向。 (C) 2010 Elsevier B.V. 保留所有权利。
Polymer nanofiber mats with various morphology structures (nanofiber, beaded-nanofiber, and composite particle/nanofiber) were prepared by electrospinning for application to aerosol particle filtration. The filtration performance of these polymer nanofiber mats was evaluated based on quality factors generated from measurement of penetration through the filter by sodium chloride (NaCl) aerosol particles ranging from 20 to 300 nm. These filtration test results showed that the quality factors of beaded-nanofiber filter mats were the best, even though the aerosol particle penetration of them was the highest of the morphology structures. The results of the present study show that morphology optimization of polymer nanofibers is an effective method for improvement of filtration performance, and it must be the future direction for development of new filtration media.
