Abstract：
ZnO nanorod nonwoven fabrics (ZNRN) were developed through hydrothermal synthesis to facilitate the prevention of the transmission of respiratory pathogens. The superhydrophobicity and antibacterial properties of ZNRN were improved through the response surface methodology. The synthesized material exhibited significant water repellency, indicated by a water contact angle of 163.9°, and thus demonstrated antibacterial rates of 91.8% for Escherichia coli (E. coli) and 79.75% for Staphylococcus aureus (S. aureus). This indicated that E. coli with thinner peptidoglycan may be more easily killed than S. aureus. This study identified significant effects of synthesis conditions on the antibacterial effectiveness, with comprehensive multivariate analyses elucidating the underlying correlations. In addition, the ZnO nanorod structure of ZNRN was characterized through SEM and XRD analyses. It endows the properties of superhydrophobicity (thus preventing bacteria from adhering to the ZNRN surface) and antibacterial capacity (thus damaging cells through the puncturing of these nanorods). Consequently, the alignment of two such features is desired to help support the development of personal protective equipment, which assists in avoiding the spread of respiratory infections.
摘要：
通过水热合成开发了ZnO纳米棒无纺布（ZNRN），以促进预防呼吸道病原体的传播。通过响应面法提高了ZNRN的超疏水性和抗菌性能。合成的材料表现出显著的防水性，水接触角为163.9°，因此对大肠杆菌的抗菌率为91.8%(E.大肠杆菌)和79.75%的金黄色葡萄球菌(S.金黄色葡萄球菌）。这表明具有较薄肽聚糖的大肠杆菌可能比金黄色葡萄球菌更容易被杀死。这项研究确定了合成条件对抗菌效果的显着影响，全面的多变量分析阐明了潜在的相关性。此外,通过SEM和XRD分析对ZNRN的ZnO纳米棒结构进行了表征。它赋予超疏水性(从而防止细菌粘附到ZNRN表面)和抗菌能力(从而通过刺穿这些纳米棒破坏细胞)的性质。因此,希望将两个这样的特征对齐，以帮助支持个人防护设备的开发，这有助于避免呼吸道感染的传播。
