Abstract
Polyamide nanofibers (nylon 6) were fabricated as core-shell structures with enriched silver nanoparticles in their shells. The main purpose of this study was to produce nanofibers with reduced silver nanoparticles content while maintaining or enhancing their antibacterial effectiveness. The coaxial electrospinning was used to fabricate the nanofibers. The core-shell solutions consisted of polyamide (caprolactam) in formic acid or acetic acid and adding silver nanoparticles into the solutions. The morphology of samples was characterized by scanning electron microscope (SEM) and the AATCC100 standard test method was used to determine the antibacterial properties of the fibers. EDAX was used to test the presence of silver nanoparticles in the samples. Finally, the new fibers' antibacterial quality was tested on Gram (-) bacteria E.Coli and Gram (+) bacteria S. Aureus. The results showed that the core-shell nanofibers were successfully produced with uniform concentration of silver nanofibers in their shells and displayed the same degree of antibacterial activity as samples with uniform distribution of nanoparticles in both the core as well as the shell structures.
