摘要
主要探讨了固化距离、纺丝电压对聚乙烯醇和淀粉、聚乙烯醇和壳聚糖共混液静电纺丝的影响,并尝试了多喷头静电纺丝制备超细长纤维复合材料。运用扫描电镜、红外光谱和差示扫描量热仪等对制得的超细复合材料的纤维形态、结构和力学性能进行研究,制得了纤维形貌与力学性能优异的、结构均匀的超细长纤维复合毡;多喷头电纺时,溶剂挥发影响着复合毡形态与性能。经过乙醇浸泡处理后,纯聚乙烯醇纳米纤维毡的结晶度和力学性能明显提高。
The effects of the solidification distance, voltage on electrospinning of the solutions of the blends of poly（vinyl alcohol） and soluble starch and of poly（vinyl alcohol） and chitosan were studied. The fabrication of ultra-fine fiber non-woven composite fabrics via multi-jet electrospinning was attempted. The morphology, structure and mechanical properties of the composite fabrics were examined by scanning electron microscopy （SEM）, infrared resonance （IR）, differential scanning calorimeter （DSC）, and tensile test. The results show that ultra-fine fiber composite mats with good fiber morphology and mechanical properties are obtained, and the volatilization of solvents affects the morphology and properties of the composite mats. Additionally, the degrees of crystallinity and mechanical properties of PVA nanofiber mats are increased after they are treated by immersing in ethanol.
