【摘要】：熔喷静电微分纺丝法是结合熔喷和无针静电纺丝的一种制备纳米纤维的方法,采用自行设计制造的熔喷-电纺喷头,通过改变气流速度和温度,分别采用熔喷、静电纺丝和熔喷-静电纺丝3种方法制备纤维,利用SEM对纤维进行表征,分析了3种纺丝条件对纤维直径和直径分布的影响。结果表明:熔喷法制得的纤维直径较细,但直径分布较宽,而无针静电纺丝法制得的纤维直径较粗,但直径分布窄,熔喷静电微分纺丝法结合了两者的优势,能制得直径小且分布均匀的纤维,最后在控制气流温度为180℃左右,气流速度为30 m/s的情况下,成功制得能够达到平均直径为300 nm的均匀超细纤维,为制备更高要求的过滤、电池隔膜和生物材料等应用方面的材料提供了一种新方法。
[Abstract]:The fusion-jet electrostatic differential spinning method is a method of preparing nanofibers by combining fusion-jet and needle-free electrostatic spinning. The fusion-electrospinning nozzle is designed and manufactured by ourselves. By changing the velocity and temperature of the airflow, the fusion-jet is used respectively. The fibers were prepared by electrostatic spinning and fusion-electrostatic spinning. The fibers were characterized by SEM. The effects of three spinning conditions on the diameter and distribution of fibers were analyzed. The results show that the fiber diameter is smaller, but the diameter distribution is wider, but the fiber diameter is larger, but the diameter distribution is narrow. The fiber with small diameter and uniform distribution can be prepared. Finally, when the temperature of the air flow is about 180 鈩，
