The COVID-19 pandemic has clearly shown the importance of developments in fabrication of advanced protective equipment. This study investigates the potential of using multifunctional electrospun poly(methyl methacrylate) (PMMA) nanofibers decorated with ZnO nanorods and Ag nanoparticles (PMMA/ZnO-Ag NFs) in protective mats. Herein, the PMMA/ZnO-Ag NFs with an average diameter of 450 nm were simply prepared on a nonwoven fabric by directly electrospinning from solutions containing PMMA, ZnO nanorods, and Ag nanoparticles. The novel material showed high performance with four functionalities (i) antibacterial agent for killing of Gram-negative and Gram-positive bacteria, (ii) antiviral agent for inhibition of corona and influenza viruses, (iii) photocatalyst for degradation of organic pollutants, enabling a self-cleaning protective mat, and (iv) reusable surface-enhanced Raman scattering substrate for quantitative analysis of trace pollutants on the nanofiber. This multi-functional material has high potential for use in protective clothing applications by providing passive and active protection pathways together with sensing capabilities.
新冠疫情清楚地表明了先进防护设备制造领域发展的重要性。本研究调查了在防护垫中使用多功能静电纺丝聚甲基丙烯酸甲酯（PMMA）纳米纤维负载氧化锌纳米棒和银纳米颗粒（PMMA/ZnO-Ag NFs）的潜力。在此，通过直接从含有 PMMA、氧化锌纳米棒和银纳米颗粒的溶液中静电纺丝，在无纺织物上简单制备了平均直径为 450nm 的 PMMA/ZnO-Ag NFs。这种新型材料具有四种功能（i）作为杀菌剂，可杀死革兰氏阴性和革兰氏阳性细菌，（ii）作为抗病毒剂，可抑制冠状病毒和流感病毒，（iii）作为光催化剂，可降解有机污染物，实现自清洁防护垫，以及（iv）可重复使用的表面增强拉曼散射基底，用于纳米纤维上痕量污染物的定量分析。这种多功能材料具有很大的潜力，可用于防护服装应用，为被动和主动防护提供途径，同时具备传感能力。
