Formation, structure, and morphology of nanofiber mat on the base sodium‐carboxymethylcellulose/polyvinyl‐alcohol/silver nanoparticles composite

Abstract

AbstractStable silver nanoparticles were synthesized in solutions containing sodium‐carboxymethylcellulose and polyvinyl alcohol, and their structure, morphology, and physicochemical properties were studied. The morphology and diameter sizes of the nanofibers of carboxymethylcellulose/polyvinyl alcohol containing silver nanoparticles were investigated using atomic force microscopy and scanning electron microscopy. The investigations showed that nanofibers with diameter sizes ranging from 50 to 130 nm were obtained from the carboxymethylcellulose/polyvinyl alcohol/silver nanoparticles solution. The size and form of silver nanoparticles formed within the solution of carboxymethylcellulose/polyvinyl alcohol based on nanofiber were determined by X‐ray diffraction (XRD), UV–visible (UV–VIS) spectroscopy, and dynamic light scattering (DLS) investigations, revealing nanoparticles with diameters ranging from 5 to 26 nm. The nanofiber mat containing silver nanoparticles exhibited significant antimicrobial activity against both Staphylococcus epidermidis and Candida albicans. The nanofiber mat containing stable silver nanoparticles could be utilized as an antimicrobial facemask for air filtration and for the treatment of burn wounds.
