Abstract
Nobel metal nanoparticles-decorated electrospun nanofibers (ENFs) have attracted great attention for different applications. In the present work, solvent-assisted mild UV treatment was introduced as a unique, efficient and versatile technique for the fabrication of honeycomb-like Ag nanoflakes-decorated electrospun PAN nanofibers. Freshly prepared electrospun PAN nanofibrous membrane from its DMF solution (without vacuum drying) was treated with AgNO3 solution under mild UV irradiation. Microscopic images showed that honeycomb-like Ag-nanoflakes were well decorated on ENFs. XRD showed the formation of amorphous silver materials on the surface of PAN fibers. The Ag nanoflakes-decorated nanofibers showed promising antibacterial properties. Therefore, this facile technique with proposed mechanism can open a new platform for the fabrication of noble metal nanospecies-decorated ENFs for different applications.
