静电纺丝是一种很有前途的制备聚合物以及金属氧化物纳米纤维的技术。在聚乙烯吡咯烷酮（PVP）聚合物中加入不同质量比（5%，7.5%和10%）的Fe3O4@Cs@Ag磁性纳米粒子，通过静电纺丝法制备磁性纳米纤维（MNF）。对所制备的纳米纤维的结构、磁性、形态、光谱和热性能进行了表征。进一步研究了Fe3O4@Cs@Ag纳米纤维膜的抗菌性能。获得的SEM图像显示所产生的纳米纤维均匀且无缺陷。利用X射线衍射仪和振动样品磁强计测试了纤维的结晶度和磁矩。结果表明，所制备的纳米纤维膜对金黄色葡萄球菌、枯草芽孢杆菌、粪肠球菌、大肠杆菌、奇异变形杆菌和铜绿假单胞菌具有良好的抗菌活性。
Electrospinning is a promising technique to produce polymeric as well as metal oxide nanofibers in diverse domains. In this work, different weight ratios (5%, 7.5% and 10%) of Fe3O4@Cs@Ag magnetic nanoparticles were added in PVP (polyvinylpyrrolidone) polymer and fabricated via electrospinning method to produce magnetic nanofibers (MNFs). Structural, magnetic, morphological, spectroscopic and thermal properties of produced nanofibers were characterized. Furtheremore, antibacterial effects of Fe3O4@Cs@Ag nanofibrous membrane was investigated. Obtained SEM images showed that produced nanofibers were uniform and defect free. Moreover, crystallinity and magnetic moment of fibers was tested by using X-ray diffraction and a vibrating sample magnetometer. The results showed that produced nanofibrous membranes exhibited good antibacterial activity versusStaphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa.
