In the present condition of COVID-19, the demand for antimicrobial products such as face masks and surgical gowns has increased. Because of this increasing demand, there is a need to conduct a study on the development of antimicrobial material. Therefore, this study was conducted on the development of Aloe Vera and Polyvinyl Alcohol (AV/PVA) electrospun nanofibers. Four different fibers were developed by varying the concentrations of Aloe vera (0.5%, 1.5%, 2.5%, and 3%) while maintaining the concentration of PVA constant. The developed samples were subjected to different characterization techniques such as SEM, FTIR, XRD, TGA, and ICP studies. After that, the antimicrobial activity of the developed Aloe Vera/PVA electrospun nanofibers was checked against Gram-positive () bacteria and Gram-negative () bacteria. The developed nanofibers had high profile antibacterial activity against both bacteria, but showed excellent results against bacteria as compared with . These nanofibers have potential applications in the development of surgical gowns, gloves, etc.
在新冠疫情当前的情况下，对面罩和手术衣等抗菌产品的需求有所增加。由于这种需求的不断增长，有必要开展一项关于抗菌材料开发的研究。因此，本研究针对芦荟和聚乙烯醇（AV/PVA）电纺纳米纤维的开发展开。通过在保持聚乙烯醇浓度不变的同时改变芦荟的浓度（0.5%、1.5%、2.5%和3%），制备了四种不同的纤维。对所制备的样品进行了扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、热重分析（TGA）和电感耦合等离子体（ICP）等不同的表征技术研究。之后，检测了所制备的芦荟/聚乙烯醇电纺纳米纤维对革兰氏阳性（）菌和革兰氏阴性（）菌的抗菌活性。所制备的纳米纤维对这两种细菌均具有高效的抗菌活性，但与相比，对细菌显示出更优异的效果。这些纳米纤维在手术衣、手套等的开发中具有潜在应用价值。
