Fabrication of Compound Nanofibers For Antibacterial Applications in Filtration
نویسنده
چکیده
In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silver (Ag) impregnated PVA while PA6 was the core material. These compound composite nanofibers were characterized extensively and the results show that nano silver resides close to the surface of the compound fibers. It is envisaged that the unique structure of the PVA-nanosilver/PA6 nanofiber can find applications in membrane and textile technologies especially in air filters in addition to other performance characteristics involving antibacterial properties. Keywords—Compound Nanofibers, Co-axial electrospinng, Nanosilver, Antibacterial activity, filtration medium.
