Assessment of the electrostatic field uniformity within an electrospinning device

The analysis carried out made it possible to evaluate the electrostatic field in an electrospinning device by means of a Comsol finite element model. The study focuses on the main factors affecting the generation of nanofibers and on the uniformity of the electrostatic field over the collector. In particular, the behaviour of the electrostatic field vector close to the needle and along the edges of the collector was assessed. Finally, the electric field at several points on the collector surface was computed in Comsol. The obtained data were processed in Matlab to assess the variation of the electric field along the x; -and y -directions. The model results allow to explain interesting aspects arising from the use of the machine.
