摘要:: 病毒的传播和由颗粒物引起的雾霾等空气污染问题已成为全球性挑战。纳米纤维膜可有效捕获空气中的颗粒物且不造成大幅压力降，因此作为一种较为理想的空气过滤介质，近年来受到了广泛关注。聚焦静电纺纳米纤维膜的制备及其在空气过滤中的应用，首先介绍了静电纺丝技术的原理及影响纳米纤维尺寸与形态的因素。其次，系统分析了纳米纤维膜的过滤机制、过滤效果评价参数及其影响因素。最后，总结了多种高效过滤策略，如引入纳米孔结构或支化结构、利用驻极体材料制备纳米纤维膜、构建多层膜复合结构等，并指明了绿色可持续化和多功能化是其未来发展方向。

Abstract:: Coronavirus transmission and air pollution caused by particulate matter have become global challenges. Nanofiber membrane filters, have attracted considerable attention as they can effectively capture particulate matter in the air without causing a large level of pressure drop. This paper mainly focuses on electrospinning nanofibers and their application in air filtration. Firstly, the principle of electrospinning technology and the factors affecting the size and shape of nanofibers were introduced. Secondly, the filtration mechanism, filtration evaluation parameters and influencing factors of nanofiber membrane were systematically analyzed. A variety of strategies to improve filtration efficiency such as the use of nano-pore structure or branched fiber morphology, electret nanofiber membrane and multi-layer structure were summarized. Finally, the prospect of green and multi-functional nanofiber air filters in the future was pointed out.
