在这项工作中，将两种圆锥形喷丝板（称为尖锥体和钝锥体）与单针喷丝板进行比较，以研究电场分布对所制备纤维的形态和机械性能的影响。根据模拟结果，实验中使用了聚苯乙烯和聚偏二氟乙烯溶液。模拟了电场分布，并用高速摄像机捕获了喷射路径。同时，对所制备的纤维的形貌和力学性能进行了表征。研究发现，由这些不同喷丝头诱导的所制备纤维的形态对机械性能有显着影响。值得一提的是，尖锥静电纺丝系统提高了纤维毡的力学性能，为纤维结构的调控奠定了基础。
In this work, two kinds of conical spinnerets, referred to as the sharp cone and blunt cone, were compared to the single needle spinneret to investigate the effect of electric field distribution on the morphology and mechanical properties of the as-prepared fibers. Based on the simulation results, polystyrene and poly(vinylidene fluoride) solutions were used in the experiments. The electric field distributions were simulated, and the jet paths were captured by a high-speed camera. Meanwhile, the morphology and mechanical properties of the as-prepared fibers were characterized. It was found that the as-prepared fibers' morphology induced by these different spinnerets had a significant influence on the mechanical properties. It is worth mentioning that the mechanical properties of fiber mats were improved from the sharp cone electrospinning system, which lays the foundation for the regulatory of fiber structures.
