In this study, clinoptilolite/PVP (Polyvinyl pyrrolidone)-zeolite composite nanofibers were synthesized using the electrospinning method. The effects of process parameters including solution concentration, spinning voltage, and spinning distance were examined on morphology and fibers diameter. Electrospun nanofibers were studied by scanning electron microscope (SEM), x-ray diffraction (XRD), and BET method. SEM images have demonstrated the steady and straight ribbon-shaped fiber from electrospinning solution with 1.8:1.8:6.4 weight ratio of clinoptilolite:PVP:ethanol, respectively. It resulted that the diameter of fabricated nanofibers is about 182 nm at 1.8:1.8:6.4 weight ratios of clinoptilolite:PVP:ethanol at a 20 cm distance and 13 kV voltage as optimal parameters. The average of fibers diameter reduced following the increase in electrospinning distance. By increasing voltage, the average of fiber diameter decreased in 15 cm distance and increased in 20 cm distance. XRD results for both particles and electrospun nanofibers show the clinoptilolite-Ca structure. The BET surface areas are measured to be 20 and 5 m² g⁻¹ for clinoptilolite particles and clinoptilolite/PVP electrospun nanofibers, respectively. Also, BET analysis showed that mesoporosity of clinoptilolite particles was preserved after putting nanoparticles inside the polymer nanofibers.

在这项研究中，使用电纺丝法合成了斜发沸石/ PVP（聚乙烯吡咯烷酮）-沸石复合纳米纤维。研究了工艺参数（包括溶液浓度，纺丝电压和纺丝距离）对形态和纤维直径的影响。通过扫描电子显微镜（SEM），X射线衍射（XRD）和BET方法研究了电纺纳米纤维。SEM图像显示了静电纺丝溶液中稳定的和直的带状纤维，斜发沸石：PVP：乙醇的重量比分别为1.8：1.8：6.4。结果表明，在20 cm距离和13 kV电压下，斜发沸石：PVP：乙醇的重量比为1.8：1.8：6.4时，制备的纳米纤维的直径约为182 nm，这是最佳参数。纤维直径的平均值随着电纺丝距离的增加而降低。通过增加电压，平均纤维直径在15厘米距离处减小，而在20厘米距离处增加。颗粒和静电纺丝纳米纤维的XRD结果均显示斜发沸石Ca结构。BET表面积经测量为20和5 m对于斜发沸石颗粒和斜发沸石/ PVP电纺纳米纤维，分别为²  g ^-1。另外，BET分析表明，将纳米颗粒放入聚合物纳米纤维后，斜发沸石颗粒的介孔性得以保留。
