1.2.3.2.1.3 Upward stationary spinnerets methods

In this needleless electrospinning setup, a novel spinneret was used that have a stepped pyramid shape (Table 7). When electric field was applied to the system, then nanofibers were generated from the edges of stepped pyramid-shaped spinneret. These nanofibers were collected on the collector that was negatively charged, placed at the top of the spinneret. Nanofiber production increased by increasing applied voltage and keeping working distance and concentration of polymer solution constant [50].
