Abstract

The present study focuses on fabrication of nanofibrous membrane to filter microbial aerosols using silver nanoparticles. Nanofibrous membrane was formed with silver nanoparticles (AgNp) and polyvinyl butyral (PVB) using electro spinning technology. The optimized nanofibers were characterized for the effective formation, morphology, and thermal sensitivity using High Resolution Scanning Electron microscopy (HR-SEM), Energy dispersive X-ray spectroscopy (EDS), and Thermo gravimetric study (TGA). Chemical components present in the aqueous leaf extract that reduces the monovalent silver were identified using Fourier Transform Infrared (FT-IR) spectroscopy. HR-SEM analysis confirmed homogenous fiber diameter with smooth surface for the obtained AgNPs-PVB membranes. The PVB loaded AgNPs have shown up to 19% weight loss at 956°C which was ascertained through TGA. Microbial loading on the filter, microbial survival, filtration efficiency, and antimicrobial efficiency of the fabricated membrane were evaluated. The fabricated membrane exhibited both bacterial and fungal filtration efficiency to an extent of 98.81% and 98.85%, respectively. Experimental data were compared theoretically using predicted mathematical model that established best fitting and was highly compatible.

绿色合成纳米银制备纳米过滤器的实验与理论验证

本研究的重点是使用银纳米粒子制备用于过滤微生物气溶胶的纳米纤维膜。采用电纺丝技术，以纳米银（AgNp）和聚乙烯醇缩丁醛（PVB）为原料制备了纳米纤维膜。使用高分辨率扫描电子显微镜（HR-SEM）、能谱仪（EDS）和热重分析（TGA）对优化的纳米纤维的有效形成、形态和热敏性进行了表征。使用傅立叶变换红外（FT-IR）光谱鉴定了存在于水性叶提取物中的还原单价银的化学成分。HR-SEM分析证实了所获得的AgNPs PVB膜的纤维直径均匀且表面光滑。负载PVB的AgNP在956°C下显示出高达19%的重量损失，这是通过TGA确定的。对所制备的膜的微生物负载量、微生物存活率、过滤效率和抗菌效率进行了评估。所制备的膜的细菌和真菌过滤效率分别达到98.81%和98.85%。使用预测数学模型对实验数据进行了理论比较，该模型建立了最佳拟合并具有高度兼容性。

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
