Ethyl cellulose(EC) nanofibers were fabricated by electrospinning of EC solution in 6-12% (w/w) concentration. Fiber morphology was observed under a scanning electron microscope and effects of instrument parameters including solution concentration, tip-target distance, flow rate and electric voltage were evaluated. With increasing the concentration of EC solution, the morphology was changed from beaded fiber to uniform fiber structure and the fiber diameter was also increased. Tip-target distance had considerable effects on fiber morphology, however, the morphology was slightly changed at high voltage. |
