dc.description.abstract | Polyvinyl alcohol (PVA) nanofibers containing Ag nanoparticles were prepared
by electrospinning PVA/silver nitrate (AgNO3) aqueous solutions, followed by short heat treatment, and their antimicrobial activity was investigated for wound dressing applications. Since PVA is a water soluble and biocompatible polymer, it is one of the best materials for the preparation of wound dressing nanofibers. After heat treatment at 155 8C for 3 min, the PVA/AgNO3 nanofibers became insoluble, while the Agþ ions therein were reduced so as to produce a large number of Ag nanoparticles situated preferentially on their surface. The residual Agþ ions were reduced by subsequent UV irradiation for 3 h. The average diameter of the Ag nanoparticles after the heat treatment was 5.9 nm and this value increased slightly to 6.3 nm after UV irradiation. It was found that most of the Agþ ions were reduced by the simple heat treatment. The PVA nanofibers containing Ag nanoparticles showed very strong antimicrobial activity. | en |
