THE SPATIAL ARRANGEMENT OF THE ELECTRIC FIELD IN THE NEEDLE-PLATE ELECTROSPINNING

The electric field distribution of the Neddle-Plate (NP) electrospinning setup has been reported
due to the simple classical electrodynamics solutions. The charge is assumed to distribute
uniformly in the collector (plate) and needle (nozzle). The electric field is only influenced in the
early stage of the electrospinning process. The electric field and the jet fluid's viscosity have
caused the straight jet's bending. The high density of the fluid can preserve the direct jet length
much longer. The electric field gives the initial angular momentum of the jet due to the whipping
motion of the jet. The electric does not influence the whipping motion for the area away from
the nozzle. Then, the whipping motion solely due to the influence of the charge repulsion of the
jet fluid and the evaporation of the solvent.
