摘　　要：利用静电纺丝技术,将具有不同聚丁二酸丁二醇酯(PBS)质量分数的纺丝溶液制备成PBS超细纤维膜。通过FE-SEM观察超细纤维膜的形貌;对质量分数均为6%的超细纤维膜和浇铸膜分别进行FT-IR、XRD和DSC观察测试,分析比较二者的结构,并进行力学性能测试。结果表明:随着PBS纺丝液质量分数的增加,其纤维平均直径从195 nm增大到389 nm;与浇铸膜相比,静电纺PBS超细纤维膜的结晶性能降低,拉伸破坏应力为18.6 MPa,小于浇铸膜的拉伸破坏应力(20.2 MPa);拉伸破坏应变约为120%,比浇铸膜的拉伸破坏应变增大近1倍。Poly（butylene succinate）（PBS） ultrafine fibrous membranes were prepared by electrospinning of PBS solutions with different mass concentrations.The morphology of ultrafine fibrous membranes was observed by field-emission scanning electron microscopy（FE-SEM）.The ultrafine fibrous membranes with mass concentration of 6% and cast membranes with mass concentration of 6% were examined by FT-IR,XRD and DSC.Analytical comparison of their structures and mechanical properties was made.The results showed that the average diameters of ultrafine fibers increase from 195 nm to 389 nm with increasing of PBS mass concentration.Compared with cast membranes,the crystallinity of ultrafine fibrous membranes decreases.Its failure stress is 18.6 MPa and lower than cast membranes,but failure strain is up to 120%,almost twice as much as that of cast membranes.
