Abstract
This research work is focused on the preparation of poly(vinyl alcohol) (PVA) nanocomposite nanofibrous mats by electrospinning method which was doped with varying concentration of Cloisite 30B and Cu-MMT nanoclays. Mechanical, physical, chemical and antibacterial properties of the nanocomposite nanofibrous mats were determined. Sodium-montmorillonite clay (Na-MMT) was modified with cupric chloride (CuCl2) through ion exchange method to form copper-montmorillonite (Cu-MMT). Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, X-ray diffraction and particle size analysis were performed to characterize the modified clay. The formation of smooth and bead-free nanoclay loaded PVA nanofibres was observed through SEM and FESEM. Both the clays loaded nanofibrous mats showed good antibacterial property against the Gram-positive bacteria and Gram-negative bacteria. These enhanced properties of the PVA nanocomposite nanofibrous mats can be used for the microbial protection applications.
