摘　　要：采用静电纺丝技术制备了PVA/Y(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PVA/Y(NO3)3复合纳米纤维在600℃焙烧10h,获得了晶态的Y2O3纳米纤维。XRD分析表明,PVA/Y(NO3)3复合纤维为无定型,Y2O3纳米纤维属于体心立方晶系,空间群为Ia3。SEM分析表明,PVA/Y(NO3)3复合纳米纤维表面光滑,平均直径约为110nm;Y2O3纳米纤维的直径约为50nm。该技术可以用来制备其他稀土氧化物纳米纤维。PVA/Y（NO3）3 composite nanofibres were fabricated by electrospinning. The optimum components of the reaction system were investigated. The influences of electrospinning technological route and experimental parameters on electrospinning process were systematically studied, and the optimum preparative conditions were obtained. Nanocrystalline Y2O3 nanofibers were synthesized by calcination of the as-prepared composite nanofibres at 600℃ for 10h. XRD results revealed that PVA/Y（NO3）3 composite nanofibres were amorphous in structure, and Y2O3 nanofibers were cubic in structure with space group Ia3. SEM analysis indicated that the surface of the PVA/Y（NO3）3 composite nanofibres was smooth, and the mean diameter of the composite nanofibres was about. 110nm. Y2O3 nanofibers were of about 50nm in diameter. This method can be applied to the preparation of other rare earths oxides nanofibers.
