【摘要】：采用熔融静电纺丝技术,利用高速滚筒制备超细取向纤维膜,以纺丝距离、纺丝电压、滚筒转速进行三因素三水平正交实验,利用扫描电子显微镜(SEM),探究各个因素对纤维取向度和纤维直径的影响,确定制备超细取向纤维膜的最优化工艺条件。同时,借助差示扫描量热仪(DSC)、拉伸实验及接触角测量仪对超细取向纤维膜的结晶性能、机械性能及疏水性进行了测试分析,并与平板接收的无序纤维膜进行对比。结果表明:当纺丝距离为10cm、纺丝电压为10kV、滚筒转速为1000r/min时,超细取向纤维表面光滑,纤维直径较小,排列紧密,具有良好的取向度,且超细取向纤维膜结晶度有所提升,水接触角变大,表现出较好的疏水性。同时,经过热压后的超细取向纤维膜机械性能明显提升。
[Abstract]:The ultrafine oriented fiber film was prepared by high speed roller with melt electrospinning technology. The orthogonal experiment was carried out in three factors and three levels, such as spinning distance, spinning voltage and rotating speed of roller. By means of scanning electron microscope (SEM), the influences of various factors on fiber orientation and fiber diameter were investigated, and the optimum process conditions for the preparation of ultrafine oriented fiber membrane were determined. At the same time, the crystallization, mechanical properties and hydrophobicity of the ultrafine oriented fiber film were tested and analyzed by means of differential scanning calorimeter (DSC), tensile test and contact angle measuring instrument, and compared with the disordered fiber film received by flat plate. The results show that when spinning distance is 10cm, spinning voltage is 10kV, rotating speed of drum is 1000r/min, the surface of ultra-fine oriented fiber is smooth, the diameter of fiber is smaller, the fiber arrangement is close, the orientation degree is good, and the crystallinity of ultrafine oriented fiber film is improved. The contact angle of water increases, showing good hydrophobicity. At the same time, the mechanical properties of the ultrafine oriented fiber film after hot pressing were improved obviously.
