Abstract
We have investigated the morphology of electrospinning nanofiber dependence on applied voltage and the influence of added ionic salts on nanofiber uniformity. For the ionic salt concentration of 0.01 mol%, the applied electric field of 10 â¼ 25Â kV, and a 15-cm spinning distance, the experimental results showed that uniform nanofibers which did not contain any beads were synthesized, while the current of electrospinning process had two orders of amount higher than the non-added ionic salt droplet current. Also the fiber diameter distribution exhibited a very narrow. We obtained uniform fibers with diameters of around 70Â nm and, exhibited electric current value for obtaining uniform high-quality nanofibers. The morphology of the electrospun nanofibers was investigated using field emission scanning electron microscopy and the electric current was measured using a digital multimeter.
