Nanofiber diameter in electrospinning of polymer solutions: Model and experiment KU Leuven
© 2016 Elsevier Ltd. A model describing nanofiber formation in electrospinning of a polymer solution is proposed. It is shown that the final nanofiber diameter is determined by the dynamics governed by two main competing factors: (i) elongation under the influence of the electric repulsion between the charges on the fiber surface, which is opposed by (ii) the viscoelastic forces growing in the course of time due to evaporation and stopping the ...
