采用静电纺丝技术制备聚酰胺6(PA6)/壳聚糖(CTS)/氯化锂(LiCl)纳米纤维膜,考察了CTS、PA6及LiCl添加量对纳米纤维膜形貌、直径分布的影响。通过场发射扫描电子显微镜、傅里叶变换红外光谱仪对纳米纤维膜的微观形貌及表面官能团进行分析。结果表明:在PA6添加量为1.8g、CTS添加量为0.3g、LiCl添加量为0.12g的条件下,纺丝效果最佳,纤维平均直径为103nm。傅里叶变换红外光谱分析表明PA6/CTS/LiCl纳米纤维膜具有PA6和CTS的特征吸收峰,PA6/CTS/LiCl纳米纤维膜有望作为滤膜材料使用。
Polyamide 6(PA6)/chitosan(CTS)/lithium chloride(LiCl) nanofiber membranes were prepared by electrospinning technique.The influences of addition of CTS,PA6 and LiCl on the morphology and diameter distribution of membranes were investigated.The microscopic morphology and surface functional groups were analyzed by field emission scanning electron microscopy and fourier transform infrared spectroscopy.The results showed that the spinning effect was the best when the added amount of PA6 was 1.8g,CTS was 0.3g and LiCl was 0.12g.The average fiber diameter was 103nm.Fourier transform infrared spectroscopy indicated that PA6/CTS/LiCl had characteristic absorption peaks of PA6 and CTS,and PA6/CTS/LiCl was expected to be used as filter materials.
