| 摘 要： | 为了改善静电纺再生丝素蛋白(SF)纤维膜的力学性能,通过静电纺丝技术制备丝素蛋白(SF)/聚丁二酸丁二醇酯(PBS)复合超细纤维膜。通过对用甲醇处理后的具有不同共混比例的超细纤维膜进行FE-SEM、FTIR、XRD和DSC观察测试,分析比较了不同共混比例的复合超细纤维膜的形貌、结构,并进行力学性能测试。结果表明:随着聚丁二酸丁二醇酯共混质量比的增加,复合超细纤维的平均直径从289 nm增大到425 nm;复合超细纤维的结晶性能随之提高;复合超细纤维膜的拉伸破坏应力先减小后增大,拉伸破坏应变逐渐增加;当共混质量比为50/50时,复合超细纤维膜表现出良好的力学性能,拉伸破坏应力接近于16 MPa,破坏应变达到50%。聚丁二酸丁二醇酯可有效调控丝素蛋白超细纤维膜的形貌、结构和力学性能。

| Abstract: | In order to improve the mechanical properties of electrospun silk fibroin(SF) ultrafine fibrous membranes,SF and poly(butylene succinate)(PBS) were dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol(HFIP) to fabricate SF/PBS composite ultrafine fibrous membranes by electrospinning.After the composite ultrafine fibrous membranes prepared by using different mass ratios of SF to PBS were treated by methanol,the morphology,structure,and mechanical properties of membranes were characterized by means of FE-SEM,FTIR,X... |
