Definition

Electrospinning is a method to fabricate nanofibers via coupled effects of electric field on viscous fluids, e.g., polymeric, ceramic, or metallic solutions/dispersions/melts. In electrospinning process, fine charged jet/jets issue from liquid surface, following elongation, evaporation, and solidification. Then solidified nanofibers can be collected.

Introduction

In the electrospinning, a micro/nano jet is generated from the solutions/dispersions/melts under electrostatic field force (EF). As shown in Fig. 1, a typical electrospinning setup consists of a high voltage source, a spinneret, a grounded collector, and a pump. The pendant droplet at the nozzle tip is deformed into a Taylor cone under the EF. As the EF overcomes the surface tension, a fine jet can be ejected from the tip of Taylor cone as illustrated in Fig. 2. After solvent volatilization, solidification, and bending instability, the charged jet can be turned into a solid...
