摘要
简述了静电纺丝原理,采用Comsol Multiphysics有限元软件对静电纺丝过程中的电场强度大小与分布进行模拟。通过改变输入电压、喷丝管直径和长度以及喷丝管与接收板的距离等试验参数,对电场强度大小与分布的影响进行了系统的研究。结果显示:电场强度最大值出现在喷丝管出口处,并且随着电压的增大,电场强度峰值增大;而随着喷丝管的直径、长度和接收距离的增大,电场强度的峰值减小。研究结果对深入理解静电纺丝的发生原理具有参考作用。
The principle of electrospinning was sketched, using finite element software Comsol Multiphysics, the value and distribution of the electric field strength in electrospinning process were simulated. By changing the different experimental parameters, such as input voltage, diameter and length of the tube, the distance between the tube and the receiver plate, the influence on the value and distribution of the electric field strength were analyzed. The results showed that the maximum field strength occured in the nozzle pipe at the outlet, and when the voltage increased, the peak value of the electric field strength increased, with increasing of the diameter, length of the nozzle tube and receive distance, the peak value of the electric field strength reduced. The results had reference value for the understanding of the principles of electrospinning.
