摘　　要：新型冠状病毒的暴发使原本国内供货充足的口罩在这场新型冠状病毒“阻击战”中成了稀缺品。而口罩所采用的滤材是决定其防护效果的关键,其中纤维的直径、形态和结构都会直接影响滤材的过滤效率和阻力压降。随着聚合物纳米纤维材料的出现以及能有效控制纤维形态和堆积结构的静电纺丝技术的发展,使得人们一直苦寻的高效低阻滤材成为可能。本文首先介绍了几种口罩用滤材及其优缺点,并通过专利分析介绍了静电纺丝技术的申请概况以及应用于口罩用聚合物纳米纤维材料制备的发展脉络。The outbreak of COVID-19 caused the original domestic supply of masks became rare product.The filter material used in the mask is the key to determine its protective effect,in which the diameter,shape and structure of the fiber will directly affect the filtration efficiency and resistance pressure drop of the filter material.With the emergence of polymer nanofiber and the development of electrospinning technology which can effectively control the fiber morphology and stacking structure,it is possible for people to search for high efficiency and low resistance filter materials.This paper firstly introduces several kinds of filter materials for masks and their advantages as well as disadvantages,and then introduces the application overview of electrospinning technology and the evolution of preparation technology on polymer nanofiber materials for masks through patent analysis.
