Analyzing factors affecting electric field intensity of electrospinning

To improve the efficiency and quality of electrospinning,a systematic simulative analysis was conducted to the electric field to study spinnerets in electrospinning.The electric field strength and its distribution were simulated using finite element analysis software Comsol Multiphysics.A comparative study was undertaken to reveal the effects of the geometry of spinneret,as well as experimental conditions,on the electric field of needle-based and needleless electrospinning.It was found that the electric field distributed on the top of the needle and over both ends of the cylinder.And the cylinder yielded stronger electric field.This study benefits further understanding of electrospinning principle and optimized design of needleless electrospinning.
