Novel polyvinylidenefluoride (PVDF) hybrid ultrafiltration membranes with antifouling and antibacterialproperties are prepared by embedding N-halamine functionalized silica nanospheres (HFSNs). With theaddition of HFSNs, the antifouling properties of PVDF membranes are significantly improved. The resultsreveal that the highest pure water permeationflux of 559.8 L m 2 bar 1 h 1 is attained when the 0.6 wt%HFSNs is added in the casting solution. The membrane of M-3 with 0.9 wt% HFSNs addition shows thehighest sterilization ratios of 97.1% and 97.0% against (escherichia coli) E. coli and (staphylococcus aureus)S. aureus respectively. After 6 times of inhibition-activation cycles, the membrane still remains 72.3%against E.coli.
