| The PVA nanofibers containing Ag nanoparticles were directly electrospun from 12 wt% PVA solutions containing Ag nanoparticles for use in wound dressing applications. The PVA solutions were prepared by refluxing PVA/AgNO3 aqueous solutions. The PVA well stabilized the resulting Ag nanoparticles during the electrospinning process. The average diameters of the PVA nanofibers electrospun with 0, 0.5, 1, and 2 wt% AgNO3 were 200, 170, 160, and 120 nm, respectively. The average diameters of the Ag nanoparticles were less than 6 nm and their size distributions were very narrow. It was found that thermal properties of PVA nanofibers could be improved by introducing small amounts of Ag nanoparticles. |
