The Influence of Changes in Voltage and Flow Rate on the Diameter of Electrospun Nanofibers

Electrospinning is a simple and cost-effective method for producing smooth and thin nanofibers. The relationship between experimental parameters and the properties of the obtained fibers is important to investigate due to their potential applications. By varying the parameter values, the desired fiber diameter and morphology can be achieved. In this study, the effect of process parameters, applied voltage and flow rate, on the morphology and diameter of fibers obtained through the electrospinning of a PCL and PEG polymer solution was examined. The results show that these parameters affect fiber diameter, with an increase in voltage generally leading to a decrease in diameter, while an increase in flow rate generally results in thicker fibers.
