静电纺丝接收装置的大小对电场分布和纤维接收的影响

为了研究接收装置对电场分布和静电纺丝纤维直径及纤维毡的影响，设计三组大小不同的接收板，分别在单针头和单孔静电纺丝装置中进行对比实验，测量纤维直径和纤维毡厚度分布。采用Maxwell软件模拟单针头和单孔静电纺丝装置中电场的分布，模拟结果用于解释分析试验结果。试验和模拟结果说明用尺寸较小的接收板的静电纺丝装置得到的纤维直径较细，纤维在接收板上的分布也较均匀，这和尺寸小接收板的静电纺丝装置电场分布均匀的模拟结果相符。因此，尺寸小的接收板可以有效地改善静电纺丝纤维的接收。

Influence of size of collector on electric field distribution and fiber receiving of electrospinning

A electrospinning setup with different sizes of collectors was developed to study the electric field distribution effects on the fiber diameter and fiber mat thickness , some contradistinctive experiments were conducted respectively in the single-needle and the single-hole electrospinning setups to measure fiber diameter and thickness distribution of fiber mats. Both single-needle and single-hole setup electric field distribution were simulated using Maxwell software,and the simulation results were used to explain the results of experiments.The results of the experiment and simulation demonstrate that more uniform electric field ,fibers with smaller diameters and more uniform fiber mats can achieved by using collectors of smaller size. Obviously，we can draw a conclusion that collectors with small size can enhance fiber receiving of electrospinning
