Functionalized Antimicrobial Electrospun Poly (vinyl alcohol) Nanowebs

Abstract

Electrospun poly (vinyl alcohol) [PVA] nanowebs functionalized with a commercially available microbiocidal solution Reputex™ 20 were prepared. The active ingredient of Reputex™ 20 is polyhexamethylene biguanides, a safe antiseptic. Fourier Transform Infrared spectroscopy confirmed the functionalization of PVA nanowebs. Functionalized nanowebs were characterized by evaluating their antimicrobial properties, breathability characteristics and tensile properties. Functionalized nanowebs demonstrated significant antimicrobial activity against both Gram positive and Gram negative bacteria. Nanowebs developed from biocompatible polymers like PVA, and functionalized with safe antiseptics, could find many biomedical applications such as wound bandages.
