(iii) whipping instability: Here, the charged jet becomes thin in the presence of an electric field, and the electric blending instability increases. Finally, the jet is solidified and collected as solid fiber on the ground collector . It is a simple technique used to produce nano-and microfiber. Electrospinning has several advantages, such as being extremely lightweight, having a low fabrication cost, having a large aspect ratio, having a reduced defect density (small diameter), having a high molecular orientation, and having high flexibility in terms of surface functionality .
