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

Stable 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.

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
