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.
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.
