摘要(Abstract)：

以聚丙烯腈(PAN)为纺丝液,采用自主设计研发的螺纹式喷头静电纺丝装置制备了幅宽为600 mm的纳米纤维膜。通过扫描电镜和孔径测定仪考察了纤维形貌以及直径分布,并测试了纳米纤维膜对0.26μm氯化钠粒子的过滤性能。结果表明:纤维的平均直径为138 nm,平均孔径为1.98μm,纤维膜平均厚度为0.025 mm;PAN纳米纤维膜过滤效率为99.899%,滤阻为280.9 Pa。
Using polyacrylonitrile(PAN) as spinning solution, the nanofiber membrane with a width of 600 mm were prepared by using a threaded nozzle electrospinning equipment which was independently designed and developed. Field emission scanning electron microscopy and pore size meter were employed to study the morphology and pore diameter of nanofiber membranes, and the filtration performance of nanofiber membranes to 0.26 μm NaCl particles was tested. The results showed that the average fiber diameter was 138 nm, the average pore diameters was 1.98 μm, and the average thickness was 0.025 mm. The filtration efficiency of the PAN nanofiber membrane was 99.899% and the pressure resistance was 280.9 Pa.
