摘要
采用熔融静电纺丝技术制备聚丙烯(PP)超细纤维,运用高速摄影技术记录了PP熔融纺丝液在高压静电场力作用下拉伸成丝的整个过程,并借助扫描电子显微镜(SEM)对不同静电压条件下所制备的PP超细纤维进行表征。实验表明,熔融静电纺射流运动大致可以分为稳定直线、分裂鞭动和沉积3个阶段。随静电压的增加,纺丝射流速度以及射流稳定直线运动区域增加,所制备纤维直径明显降低。
Polypropylene ultrafine fibers were made by melt electrospinning.The jet path of melt spinning was recorded using high-speed photography and the morphology of PP fibers were characterized by scanning electron microscopy（SEM） at different voltages.The results indicated that the spinning jet can be approximately divided into three stages： straight line,splitting and whipping,and deposition.As the voltage increased,the spinning jet speed and the length of straight line increased,and the diameter of fibers decreased obviously.
