摘　　要：为对静电纺聚丙烯纤维进行亲水改性,采用表面活性剂吐温20,通过熔融微螺杆挤出机对等规聚丙烯进行熔融共混亲水改性,并通过静电纺丝的方法制备了聚丙烯纤维。通过傅里叶变换红外光谱分析、X射线光电子能谱分析和静态接触角测试对表面活性剂改性聚丙烯纤维的表面化学性质进行了表征,并使用差示扫描量热法对静电纺聚丙烯纤维进行了热力学性能测试。红外图谱显示表面活性剂吐温20已与聚丙烯共混成功,且改性后的聚丙烯纤维在表面活性剂吐温20添加量达到3%之后,静态水接触角明显降低,添加量达到5%时,接触角瞬间为零,展现出极好的吸湿性。X射线光电子能谱分析结果表明,表面活性剂吐温20富集在聚丙烯纤维的表面。For the hydrophilic modification of isotactic polypropylene（ PP）,PP / Tween-20 blends were mixed via a melting micro-screw extruder,then the blends were electrospun to fibers. The PP / Tween-20 electrospun fibers were performed by attenuated total reflection Fourier-transform infrared（ ATR FT-IR）spectroscopy, X-ray photoelectron spectroscopy（ XPS） and contact angle measurements. The thermodynamics of electrospun fibers were measured by differential scanning calorimetry analysis. FT-IR spectra indicated PP had been blended with surfactant Tween-20. After blending with surfactant Tween-20,the contact angle of the electropsun fibers was reduced considerably especially when the load of surfactant Tween-20 was up to 3%. The electropsun fibers exhibited excellent hygroscopicity. The contact angle up to zero instantaneously,when the load was 5%. XPS results demonstrated substantial enrichment of the surfactant Tween-20 segments on the surfaces.
