Antimicrobial agent treatment is needed to prevent airborne infections due to microorganisms causing diseases. Silver nanowires (AgNW) have been increasingly used in air filters for their superior antimicrobial performance. In this study, AgNWs (115 nm in diameter, 4–50 µm in length) were electrosprayed on the surface of polyacrylonitrile (PAN) fibres that were obtained by electrospinning. Filtration efficiency of the AgNW-coated fibres was tested by aerosolizing and convectively delivering test bacteria and virus particles to the fibres. Then the particles filtered on the fibres were cultured to evaluate antibacterial and antiviral abilities. The overall filtration efficiency of the fibres increased from 92% to 96.5% (at 2.5 $\mathrm{cm}$/s of air velocity) to 98.3–99.6% after AgNW coating for 30 min (areal density = 2.352 μg per 1 ${\mathrm{cm}}^2$ of filter surface area), without affecting the pressure drop. The AgNW coating for 30 min significantly increased the antimicrobial efficiency to 98.0 $\pm$ 1.1% for Staphylococcus aureus (S. aureus), 95.2 $\pm$ 2.6% for Bacillus cereus (B. cereus), 93.7 $\pm$ 1.5% for Micrococcus luteus (M. luteus), and 72.5 $\pm$ 1.9% for bacteriophage MS2.

需要进行抗菌剂治疗，以防止由于微生物引起疾病而导致的空气传播感染。银纳米线（AgNW）因其卓越的抗菌性能而越来越多地用于空气过滤器中。在这项研究中，将AgNW（直径115 nm，长度4-50 µm）电喷涂在通过静电纺丝获得的聚丙烯腈（PAN）纤维表面上。通过将测试细菌和病毒颗粒雾化并对流输送到纤维中，测试了涂覆有AgNW的纤维的过滤效率。然后，将过滤在纤维上的颗粒进行培养，以评估其抗菌和抗病毒能力。纤维的总过滤效率从92％提高到96.5％（在2.5下$\mathrm{厘米}$AgNW涂层30分钟后，风速/ s达到98.3–99.6％（面密度= 2.352μg/ 1 ${\mathrm{厘米}}^2$过滤器表面积）），而不影响压降。AgNW涂层30分钟可将抗菌效率显着提高至98.0 $\pm$金黄色葡萄球菌（S. aureus）的 1.1％， 95.2 $\pm$蜡样芽孢杆菌（B. cereus）  2.6％， 93 。7 $\pm$黄褐球菌（M. luteus）的 1.5％和72.5 $\pm$ 噬菌体MS2为1.9％。
