Polymer Concentration Effect on Nanofiber Growth Using Pulsed Electrospinning

Abstract

In this paper, a new electrospinning device is designed and fabricated based on the pulsed system. The general model of electrospinning process is represented. Moreover, the produced nanofibers are characterized by Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR). The effects of concentration and voltage depended on the collector rotation are investigated on the electrospinning process. The three different polystyrene solutions with the three various voltages are used to produce several polymer nanofibers. The experimental results reveal that the increase in polymer concentration enlarges the thickness of nanofiber while increase in applied voltage causes to decrease the nanofiber thickness. The results are compared with similar research. For our research, we applied the 10 KV voltage instead of 20 KV voltage as indicated in the literature. The measured results show that the proposed model has good adjacency with respect to analytical and experimental data.
