Research output: Contribution to specialist publicationArticle


The electrospinning process used for producing continuous polymeric fibers with diameters in the nanometer range, uses high voltage electric field to produce high surface area submicron fibers. An experimental trial was conducted to produce nanofibers with Polyethylene Oxide (PEO) solution. The apparatus used for electrospinning consisted of a high voltage electric source with positive or negative polarity, a syringe pump with capillaries or tubes to carry the solution from the syringe or pipette to the spinnerette, and a conducting collector. The results of the experiment showed that a critical voltage of above 5 KV was required to overcome the surface tension, and continuous stable jets were formed only above 7 KV. The deposition rate increased with an increase in the velocity of fiber jets by increasing the applied voltage. The results also showed that the solvent effect plays an important role in the formation of defect free fibers. The trials have confirmed that the electrospinning process is a viable method to produce fibers in the nanometer range.
