摘　　要：研究多面体倍半硅氧烷(POSS)改性聚氨酯纳米复合材料的制备方法,并采用静电纺丝技术制备POSS-PU纳米纤维膜.通过改变纺丝电压、纺丝液浓度、接收距离、挤出速率、POSS浓度,借助扫描电子显微镜分析了各参数对纤维形貌的影响.分析结果表明:DMF/THF混合溶剂质量比为1∶2、电压为20 k V、接收距离为20cm和挤出速率为0.8 m L/h时所制得的纳米纤维膜形貌最好.而且POSS的加入有助于纳米纤维的细化.The polyurethane nanocomposites modified by POSS was obtained. Then POSS-PU nanofibers were prepared by electrospinning technique. The effects of the parameters on the morphology of the fibers were analyzed by changing the spinning voltage, the concentration of the solution, the receiving distance, the extruding speed and the concentration of POSS. The results show that the morphology of nanofiber membrane is the best when the mass ratio of DMF/THF mixed solvent is 1∶2, the voltage is 20 k V, the receiving distance is 20 cm and the extruding speed rate is 0.8 m L/h. Adding POSS into polyurethane is helpful to the refinement of the nanofibers.
