熔体静电纺丝3D电场模拟

采用有限元分析软件ANSYS对熔体静电纺丝平台模型进行三维电场模拟。分析了纺丝系统在不同电压下的电场分布情况，重点讨论了内锥面喷头间距对纺丝尖端电场的影响。发现在间距为100mm时，内锥面喷头纺丝尖端场强分布最为均匀|纤维路径上的场强随着喷头数量、施加电压的增加而增加，随着喷头间距增加无明显变化；场强较强处出现在纺丝尖端和接收板边缘。在模拟基础上研发了新型一分四的熔体微分静电纺丝机，制备了均匀分布的纤维，为进一步设计纳米纤维宏量化生产的纺丝设备提供参考。

3D electric field simulation of melt differential electrospinning

This study utilizes the finite element analysis software ANSYS to simulate a melt differential electrospinning system. The field distribution under different voltages is analyzed and the effects of changing the inner cone nozzle interval on the electric field strength of the spinning edge are discussed. The simulation results indicated that: the spinning edge had a uniform electric field distribution when the interval was 100 mm|with increasing the number of nozzles and applied voltage, the electric field of the fiber route increases, without any obvious response when changing the interval of the nozzles|the electric field intensity was a maximum on both the edge of the nozzle and the receiving board. In addition, and based on the simulation, a novel melt differential electrospinning device was developed and fibers were fabricated, and the results provide guidance for the design of future electrospinning systems for the mass production of nanofibers. 
