摘　　要：采用静电纺丝法制备了PVP/[Zn(NO3)2+Fe(NO3)3]复合纳米纤维,研究了反应体系的最佳组成,系统地讨论了静电纺丝工艺的影响,获得了最佳制备条件。将PVP/[Zn(NO3)2+Fe(NO3)3]复合纳米纤维在600℃焙烧5h,获得了晶态的ZnFe2O4纳米纤维。XRD分析表明,ZnFe2O4纳米纤维属于单相尖晶石结构,空间群为Fd3m。SEM分析表明,PVP/[Zn(NO3)2+Fe(NO3)3]复合纳米纤维表面光滑,平均直径约为200nm,ZnFe2O4纳米纤维的直径为175nm。PVP/PVP/[Zn（NO3）2＋Fe（NO3）3] composite nanofibers were prepared by electrospinning. The optimum components of the reaction system were studied. The influences of electrospinning technological route and experimental parameters on electrospinning process were systematically investigated, and the optimum preparative conditions were acquired. Crystalline ZnFe2O4 nanofibers were fabricated by calcination of the as-prepared composite nanofibers at 600℃ for 5h. XRD resuits revealed that ZnFe204 nanofibers possessed single phase spinel-typed structure with space group Fd3m. SEM analysis indicated that the surface of the PVP/[Zn（NO3）2＋Fe（NO3）3] composite nanofibres was smooth, and the mean diameter of the composite nanofibers was about 200nm. ZnFe2O4 nanofibers were of about 175nm in diameter.
