Electrospinning: theoretical foundations and processing parameters

Abstract

Electrospinning is an efficient procedure for nanofibers fabrication from a liquid jet through a nozzle under the electrostatic field. A theoretical framework is established for the understanding of the physical mechanisms of electrospinning with parameter regimes prediction. A slender-body theory for stretched and charged jet was applied to this problem. For the steady electrospinning process, a jet profile was determined numericaly. A linear stability analysis of axisymmetric perturbation of the electric jet is presented. The dynamics model of the jet bending is derived and solved numerically for the PEO solution. The important electrospinning processing parameters are optimised using the response surface methodology based on experimental data. Useful operating diagrams in volume flux-electric field space are discussed.
