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 130×104 and zinc acetate with mass fraction of 10%,receiving distance was 13cm,solution feeding rate was 0.6mL/h,voltage was 17kV,and calcination temperature was 550℃.
