摘要：Electrospinning system with single needle and planar collector has the disadvantage of a low productivity. To overcome this problem drum collector and multi-nozzle system were employed. The multi-nozzle system was used to improve the production rate, while the drum collector was used for maintaining the uniformity of the size. The purposes of this study were to examine the influence of electric field in the electrospinning process and to control the morphology of the obtained poly(vinyl alcohol)/PVA nanofibers by changing the solution flow rate. The obtained results were: (1) PVA nanofibers membrane have been successfully produced stacked on the drum collector, (2) distortion of the electric field at the tip of the needle was occurred, which results in inhomogeneous thickness of the stacked nanofibers, and (3) the morphology of the obtained nanofibers at the flow rates of 0.4 and 0.6 ml/hour have many beads while at 0.8 ml/hour the number of beads decreased.
