摘要(Abstract)：

对含有NaCl、KCl、Na2SO4、Na2CO3的聚乙烯醇(PVA)溶液进行静电纺丝,成功制备出含盐PVA纳米纤维膜。通过扫描电子显微镜(SEM)对各纤维膜的形貌进行表征,发现这些无机盐的加入对PVA纳米纤维的形貌造成明显影响,如纤维之间发生粘连或扁平带状纤维。此外通过单轴拉伸对各纤维膜的力学性能进行测试,结果表明:少量NaCl、KCl、Na2SO4或Na2CO3的加入,可以明显提高PVA纳米纤维膜的力学性能。进一步通过热失重分析(TGA)对各纤维膜热稳定性的考察表明:NaCl、KCl、Na2SO4的加入可以有效提高PVA纳米纤维膜的热稳定性,而Na2CO3的加入则对PVA纳米纤维膜的热稳定性无明显提高。
Poly(vinyl alcohol)(PVA) nanofiber mats containing different inorganic salts such as NaCl,KCl,Na2 SO4 and Na2 CO3 are successfully prepared by electrospinning.Through tensile test and thermogravimetric analysis(TGA),it is found that the addition of small amount of different inorganic salts can greatly improve the mechanical properties and thermostability of PVA nanofiber mats.Besides,the addition of inorganic salts have obvious effects on the morphology of PVA nanofiber which is determined by scanning electron microscope(SEM).
