Abstract

Electrospinning is a process that creates nanofibers through an electrically charged jet of polymer solution or polymer melt. The value of the technology lies in the smallest fiber diameters that can be fabricated because nanofibers offer more performance advantages in many fields as their diameters decrease. Many parameters, which are classified broadly into solution parameters, process parameters, and ambient parameters play significant roles in determining the morphology and diameter of electrospun nanofibers. In order to be able to have a control on fiber diameter, it is important to investigate the parameters that influence it. In this study, an attempt is made to investigate the effect of needle diameter on the resulting electrospun SF average nanofiber diameter by using four different needle gauges. The resulting nanofibers were analyzed by scanning electron microscopy (SEM) and statistically significant decrease in nanofiber diameter was observed in response to the decrease in needle diameter.
