Abstract：
UNASSIGNED: Wearing protective face masks and respirators has been a necessity to reduce the transmission rate of respiratory viruses since the outbreak of the coronavirus (COVID-19) disease. Nevertheless, the outbreak has revealed the need to develop efficient air filter materials and innovative anti-microbial protectives. Nanofibrous facemasks, either loaded with antiviral nanoparticles or not, are very promising personal protective equipment (PPE) against pandemic respiratory viruses.
UNASSIGNED: In this review, multiple types of face masks and respirators are discussed as well as filtration mechanisms of particulates. In this regard, the limitations of traditional face masks were summarized and the advancement of nanotechnology in developing nanofibrous masks and air filters was discussed. Different methods of preparing nanofibers were explained. The various approaches used for enhancing nanofibrous face masks were covered.
UNASSIGNED: Although wearing conventional face masks can limit viral infection spread to some extent, the world is in great need for more protective face masks. Nanofibers can block viral particles efficiently and can be incorporated into face masks in order to enhance their filtration efficiency. Also, we believe that other modifications such as addition of antiviral nanoparticles can significantly increase the protection power of facemasks.

摘要：
■自从冠状病毒（COVID-19）疾病爆发以来，佩戴防护口罩和呼吸器一直是降低呼吸道病毒传播率的必要条件。然而，疫情表明需要开发高效的空气过滤材料和创新的抗微生物保护剂。纳米纤维面罩，要么装载抗病毒纳米颗粒，要么不装载，是非常有前途的个人防护设备（PPE）对抗大流行性呼吸道病毒。
■在这篇评论中，讨论了多种类型的面罩和呼吸器以及颗粒物的过滤机制。在这方面,总结了传统口罩的局限性，并讨论了纳米技术在开发纳米纤维口罩和空气过滤器方面的进展。解释了制备纳米纤维的不同方法。覆盖了用于增强纳米纤维面罩的各种方法。
■尽管戴常规口罩可以在一定程度上限制病毒感染的传播，世界非常需要更多的防护口罩。纳米纤维可以有效地阻断病毒颗粒，并可以掺入面罩中以提高其过滤效率。此外，我们认为，其他修饰，如添加抗病毒纳米颗粒，可以显着提高口罩的保护能力。
