摘　　要：为了研究电场分布对静电纺丝纤维直径的影响,设计一种以孔代替针头的平面三孔静电纺丝装置,与传统三针头静电纺丝装置进行对比试验,同时用Maxwell软件对两种静电纺丝装置的电场分布进行模拟.试验与模拟结果表明:以孔代替针头的纺丝装置中的电场分布更加均匀,所纺纤维直径更小且分布更加均匀.A electrospinning setup with holes instead of needles on the spinneret was developed to study the electric field distribution effects on the fiber diameter and some contradistinctive experiments were conducted between the conventional three-needle electrospinning and the three-hole electrospinning. Electric field distribution was simulated using Maxwell software. The results of the experiment and simulation demonstrate that the novel electrospinning with more uniform electric field can produce fibers with smaller diameters and more uniform distribution.
