PVP/Zn (Ac )2 composite nanofibers are synthesized by electrospinning method, and the morphology of the nanofibers is characterized via scanning electron microscopy(SEM).The effects of PVP content,spinning voltage and zinc acetate content on the spinning process and the fiber morphology are investigated in detail.Meanwhile,the reasons for different parameters caused the change of the fiber morphology are analyzed.The results show that the smooth and continuous PVP/Zn (Ac)2 composite nanofibers with average diameter of about 180 nm can be obtained when PVP content is 0.248 g in 2 mL ethanol,zinc acetate content is 0.501 g in 2.5 mL DMF and spinning voltage is 17 kV.It realizes the controllable preparation of ZnO precursor nanofibers.
