摘　　要：为克服纳米ZnO颗粒在抑菌和有机污染物去除方面的应用局限性,采用静电纺丝技术制备出乙酸锌/聚乙烯吡咯烷酮[Zn(Ac)_(2)/PVP]纳米纤维,通过高温煅烧得到ZnO纳米纤维。在实验室条件下,对静电纺制备ZnO纳米纤维材料的工艺参数,如溶剂、聚合物、进液速度、电压、煅烧终温及升温程序等进行了优化,并通过扫描电子显微镜、X射线粉末衍射仪和X射线能量色散谱仪对材料的性能进行了表征。实验结果表明以二甲基甲酰胺为溶剂,相对分子质量为130×10^(4)、质量分数为10%的PVP和Zn(Ac)_(2)为溶质,在接收距离为13cm、进液速度为0.6mL/h、电压为17kV、煅烧温度为550℃条件下,得到形貌良好、数量多和粒径均一的ZnO纳米纤维。In order to overcome the inhibition of ZnO nanoparticle materials in sterilization and organic pollutants oxidation,the ZnO nanofibers and Zn(Ac)_(2)/PVP nanofibers were prepared by electrospinning method.Zn(Ac)_(2)/PVP nanofibers were then calcined at high temperature to obtain ZnO nanofibers.The process parameters for the electrospinning preparation of ZnO nanofiber were optimized under laboratory conditions,including solvent,polymer,and solution feeding rate,voltage intensity,final temperature of calcination and heating procedure,etc.Then the synthetic material\s properties were characterized by SEM,XRD and EDS.It was found that ZnO nanofibers with excellent morphology,large quantity,and uniform particle size can be obtained by the following conditions:the solvent was dimethylformamide,solutes were PVP with a relative molecular mass of 130×10^(4)and zinc acetate with mass fraction of 10%,receiving distance was 13 cm,solution feeding rate was 0.6 mL/h,voltage was 17 kV,and calcination temperature was 550℃.
