静电场中PVA/PA6复合纳米纤维的成型性研究

摘要

为制备一种在包装和过滤领域有着良好应用前景的先进复合材料,采用静电纺丝的方法制备出PVA/PA6复合纳米纤维,对其在静电场中的成型性进行了系统的分析与研究.研究结果表明,随着溶液质量分数的增加,纤维的形貌变好,直径变粗;随着纺丝电压与喷丝流量的增加,纤维的平均直径变细,珠状物逐渐减少;随着接收距离的增加,纤维的平均直径变粗,珠状物增多.%PVA/PA6 composite nanofibers were prepared by electrospinning in order to process one kind of advanced composite material which has a good application prospect in packaging, filtrating and other fields. The formability of the composite in the electro- static field was analyzed and researched. The result showed that the prepared nanofibers morphology are very good and their average di- ameters were increased with the increase of the mass fraction of the solution, their diameters and the beads amount were decreased with the increase of spinning voltages and flow rates, the average diameter of the nanofibers were increased and the beads amount were in- creased with the increase of the receiving distances.
