摘　　要：采用静电纺丝技术制备了聚乙烯吡咯烷酮(PVP)纳米纤维,研究了浓度、电压等实验条件对纤维形貌的影响。SEM分析表明:随浓度和电压不断升高,纤维形貌呈现规律性的变化。在浓度和电压较高的情况下,首次制备了空心管束结构的PVP纳米纤维。TGA-DTA分析表明:632.92℃纤维完全被氧化。XRD表明:制备的PVP纤维为无定型态。。PVP nanofibers were prepared by electrospinning techniques, the effects of concentration and applied voltage on morphology of electrospun fibers were investigated. SEM analysis indicated that the morphology of fibers changed regularly with increase of PVP concentration and applied voltage. The structure of hollow nanotube bundle was first reported at high PVP concentration and applied voltage. TGA-DTA result indicated nonwoven mat was oxidized completely before 632.92℃. XRD analysis showed that the PVP nonwoven mat was amorphous in structure.
