摘要: 双喷头静电纺丝过程中,喷头间电场相互干扰,带有相同电荷的两条射流相互排斥,使得纺丝连续性下降且纤网分布不均匀。本文通过在两喷头处各装有相同形状的圆锥形辅助电极来降低电场间的干扰,实验表明,装有圆锥形辅助电极的双喷头静电纺丝射流连续性好,纤网分布均匀且纤维直径更细。最后通过Ansoft Maxwell 3D电磁场分析软件对静电纺丝电场进行建模仿真,并模拟射流受力,从而进一步阐明辅助电极屏蔽电场的作用。

Abstract: In general, two jets bend outward because adjacent electric fields interfere with the other in the double-needle electrospinning process. Therefore, the continuity of electrospinning process and the evenness of fiber web decrease. This paper focuses on dual-nozzle electrospinning device, and two in the spinning process the fiber spray nozzle with the same charge as the mutually exclusive, exacerbated the instability of the jet, making the fiber web distribution uneven. On this basis, we designed a variety of auxiliary electrodes to stabilize the jet, uniform fiber network. By Ansoft Maxwell 3D electromagnetic field analysis software for modeling and analysis to explain why the auxiliary electrode can play such a role for the further development of electrospinning.
