A new circular spinneret system for electrospinning numerical approach and electric field optimization

摘要

Electrospinning is believed to be the most effective technique to produce microfibers or nanofibers at large scale, which can be applied in various hightech areas, including energy harvester, tissue engineering, and wearable sensors. To enhance nanofiber throughput during a multi-needle electrospinning process, it is an effective way to keep the electric field uniform by optimizing electrospinning spinnerets. For this purpose, a novel circular spinneret system is designed and optimized numerically by a 3-D finite element model, the optimal collector shape is also obtained.
