Fabrication and catalytic behavior of hierarchically-structured nylon 6 nanofiber membrane decorated with silver nanoparticles

A hierarchically-structured Ag/nylon 6 (PA6) nanofiber membrane with thick fibers which acted as supports and thin fibers which provide high specific surface area was fabricated via electrospinning and impregnation method. The special structure endows the membrane high specific surface area and that contribute to the loading and dispersion of Ag NPs. Compared with normal Ag/PA6 nanofiber membrane (Ag/PA6 NM), the HS-Ag/PA6 NM with higher specific surface area exhibits improved degradation rate of methylene blue (MB) from 81.77% to 98.13% within 2 h.
