摘　　要：Antimicrobial poly( vinyl alcohol)( PVA) nanofibrous composites were prepared by adding 3-( 2,3-dihydroxypropyl)-5,5-dimethylimidazolidine-2,4-dione( N-halamine diol) to the PVA solution using electro-spinning technique upon curing and exposure to diluted sodium hypochlorite. Scanning electron microscopy( SEM) demonstrates that PVA nanofibers formed with diameters of( 255 ±94) nm. Cross-linked PVA nanofibers with N-halamine diol precursor and 1,2,3,4-butanetetracarboxylic( BTCA) showed good water resistance. The chlorinated PVA nanofibrous mats completely inactivated Staphylococcus aureus( Gram-positive) and Escherichia coli O157: H7( Gram-negative) with 7 log reductions( the reduction of the bacterial concentration in logarithm) within 5min and 1 min of contact time,respectively.Antimicrobial poly （ vinyl alcohol ） （ PVA ） nanofibrous composites were prepared by adding 3-（2,3-dihydroxypropyl） -5,5- dimethylimidazolidine-2,4-dione （ N-halamine diol ） to the PVA solution using electro-spinning technique upon curing and exposure to diluted sodium hypoclflorite. Scanning electron microscopy （SEM） demonstrates that PVA nanofibers formed with diameters of （255 ± 94 ） nm. Cross-linked PVA nanofibers with N-halamlne diol precursor and 1, 2, 3, 4-butanetetracarboxylic （BTCA） showed good water resistance. The chlorinated PVA nanofibrous mats completely inactivated Staphylococcus aureus （Gram-positive） and Escherichia coli O157 ： H7 （Gram-negative） with 7 log reductions （ the reduction of the bacterial concentration in logarithm） within 5 vain and I rain of contact time, respectively.
