Optimizing Chitosan/TFA electrospinning Parameters in order to Achieve Free-beaded Chitosan Nanofibers

Electrospinning parameters such as solution concentration, applied voltage, flow rate and distance between needle tip and collector were investigated, and optimized in order to fabricate bead-free chitosan nanofibers. Scanning electron microscope (SEM) was used to determine the fiber structure quality and analyze the effect of each mentioned processing parameters. It was found that the best conditions to access fine chitosan nanofibers from Chitosan/TFA solutions is 3.25 wt% in concentration, an applied voltage of 20kv, 0.3ml/hr of flow rate and a needle to collector distance equal to 10 cm
