静电纺丝方法收集的一维微米或纳米级纤维是随机取向的,这限制了它的应用。本研究使用辅助电极控制纺丝过程中纤维分布而使纤维取向。由于辅助电极形成的静电场是一个会聚电场,从而控制了旋转收集滚筒上纤维的分布。结果表明,平行辅助电极使电纺毡纤维密度明显提高,而纤维平均直径没有明显的变化。可见,在旋转的收集滚筒上使用辅助电极是控制纤维分布的有效方法。 Electrospinning method to collect the one-dimensional micron or nanofibers are randomly oriented, which limits its application. In this study, an auxiliary electrode was used to control the fiber distribution during spinning to orient the fibers. Since the electrostatic field formed by the auxiliary electrode is a converging electric field, the distribution of the fibers on the rotary collecting drum is controlled. The results showed that the parallel auxiliary electrode increased the density of electrospun fiber obviously, while the average fiber diameter did not change obviously. As can be seen, the use of an auxiliary electrode on a rotating collecting drum is an effective way to control the fiber distribution.
