摘要

以N

N-二甲基甲酰胺/异丙醇为溶剂

采用高压静电纺丝技术制备了EVOH-g-nSPEG无纺布.考察了混合溶剂配比、纺丝液浓度、电压、板间距等因素对产物的影响

并用扫描电子显微镜(SEM)分析研究了薄膜的微观形貌

用电子万能试验机测定了其拉伸性能

最终获得了EVOH-g-nSPEG的较佳制备工艺.结果表明

当纺丝液复合溶剂N

N-二甲基甲酰胺/异丙醇配比为8/2

纺丝液浓度为18%(w/v)且电压和板间距在一定范围内时制得的EVOH-g-nSPEG无纺布的力学性能良好

其拉伸强度均介于11.4~12.3MPa.

Abstract

The poly(ethylene co-vinyl-alcohol)(EVOH) non-wovens were prepared by electrospinning with mixed spinning solvents of N

N-dimethylformamide and iso-propanol.The ratio of mixed solventsthe

concentration of spinning liquid

spinning voltage and capillary-screen distance were studied.The micro-morphology of the non-wovens was analyzed by SEM.Its tensile properties was determined by electronic universal testing machine

and the better preparation technology was obtained.The results indicate that the EVOH non-wove...
