Nanosilver particle has been used in the nanofiber mats by mixing the nanosilver with the spinning solution for improving the
antibacterial property. Although studies have shown that the antibacterial property of nanofiber mats gets increasing, the higher
silver content and the larger released resistance of nanosilver from nanofiber mats are obvious. Here, the electrospinning-combined
postdeposition method was used to prepare the nanosilver/sericin/poly(ethylene oxide) (Ag/SS/PEO) nanofiber mats and the
bacterial reduction rates against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) were analyzed. We found that the
Ag/SS/PEO nanofiber mats were excellent antibacterial properties at the lower silver content and the bacterial reduction rates
against S. aureus and E. coli all reached above 99.99%. Our data suggests that the antibacterial property can be improved by
introducing the electrospinning-combined postdeposition method.
