  Abstract

The electric field and temperature are the two important factors that influence the diameter and properties of fiber in the melt electrospinning process. It is commonly known that the polymer jet behavior is governed by the electric field within spinning area. In present work, a comprehensively-designed and properly-conducted analysis was carried out to investigate into the effects of electric field on the jet behaviors, diameters, crystalline structure and mechanical properties of the resultant fibers. An auxiliary electrode was invited to enhance the electric field strength. The high-speed photography was adopted to capture the jet motion, and also, the numerical simulation was used to understand the electric field distribution. By making use of the whipping amplitude and whipping frequency, the characteristics of jet behavior were described. It was found that by applying an auxiliary electrode, the average fiber diameter reduced from 61.01 關m to 9.06 關m, and the crystallinity and strength of the fiber was improved with the help of the higher electric filed intensity. In addition, the more uniform electric field would produce finer and more uniform fiber because of the more stable jet motion.
