摘要: 通过混杂静电纺丝的方法,纺制了再生丝素蛋白(SF)/聚丁二酸丁二醇酯(PBS)不同混杂质量比的超细纤维,通过对不同混杂质量比的复合超细纤维膜经甲醇处理后进行FE-SEM、 FTIR和XRD观察与测试,分析比较了不同混杂质量比的复合超细纤维膜的形貌与结构,并进行力学性能测试。结果表明:不同混杂质量比的超细纤维形貌相似、纤维均匀良好。随着混杂复合超细纤维膜中聚丁二酸丁二醇酯含量的增加,混杂复合超细纤维膜整体的结晶性能变好,拉伸破坏应力和应变也逐渐增加,当SF/PBS混杂质量比从90/10变为50/50时,拉伸破坏应力从15.2MPa增加17.3MPa,且拉伸破坏应变从2.1%增大到38.2%,相比于静电纺纯丝素蛋白超细纤维膜,混杂复合超细纤维膜表现出良好的力学性能。

Abstract: The silk fibroin (SF) and Poly (butylene succinate) (PBS) were respectively dissolved in 1, 1, 1, 3, 3, 3-hexafluoro-2-propanol (HFIP) to fabricate SF/PBS hybrid composite ultrafine fibrous membranes of different mass ratios by electrospinning. The hybrid composite ultrafine fibrous membranes prepared by using different mass ratios of SF and PBS were treated by methanol, The morphology of membranes were observed by field-emission scanning electron microscopy (FE-SEM). The structure and mechanical properties were characterized by means of FTIR, XRD, and Instron 5543 tensile tester. The results show the morphology of hybrid ultrafine fibers with different mass ratio was similar and uniform. Mechanical properties and the crystallinity of the hybrid composite ultrafine fibrous membranes are increased with the addition of PBS. when the hybrid mass ratio increases from 90/10 to 50/50, failure strength increases from 15.2MPa to 17.3MPa and failure elongation increases 2.1% to 38.2%. Compared with electrospun silk fibroin ultrafine fibrous membranes, hybrid composite ultrafine fibrous membranes show good mechanical properties.
