摘要:

病毒的傳播和由顆粒物引起的霧霾等空氣污染問題已成為全球性挑戰。納米纖維膜可有效捕獲空氣中的顆粒物且不造成大幅壓力降，因此作為一種較為理想的空氣過濾介質，近年來受到了廣泛關注。聚焦靜電紡納米纖維膜的制備及其在空氣過濾中的應用，首先介紹了靜電紡絲技術的原理及影響納米纖維尺寸與形態的因素。其次，系統分析了納米纖維膜的過濾機制、過濾效果評價參數及其影響因素。最后，總結了多種高效過濾策略，如引入納米孔結構或支化結構、利用駐極體材料制備納米纖維膜、構建多層膜復合結構等，并指明了綠色可持續化和多功能化是其未來發展方向。

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.
