静电纺尼龙6/聚氧化乙烯复合纳米纤维毡的制备和性能测试

以尼龙6(PA6)/聚氧化乙烯(PEO)为原料配备复合纺丝液,通过高压静电纺丝制备出不同原料比例复合纳米纤维毡,再将纳米纤维毡进行水洗处理。应用电子显微镜(SEM)、原子力显微镜(AFM)观察分析纳米纤维毡经水洗处理前后的整体及单根纤维形貌。分析纳米纤维膜水洗前后孔隙率变化,同时通过亚甲基蓝吸附测试说明纳米水洗处理对纳米纤维毡吸附性能的影响。结果表明,PEO含量会对纳米纤维膜形貌、比表面积、孔隙率、吸附性能产生影响,而水洗处理会使纳米纤维的这些性能发生变化。

Preparation of PA6/PEO Composite Nanofiber Membrane and Performance Test

PA6/PE0 composite nanofiber membranes were prepared with different PA6/PEO massration through high voltage electrospinning and wash the membranes in water.According to the SEM and AFM images,the surface characteristics of the membranes and single nanofiber were affected after washing.The porosity test shows that both the washing process leads to a lower porosity generally and the and the adsorption property is affected either. It is concluded that the surface characteristics,porosity and absorption property...
