| Résumé : |
We investigate effects of electric current on formations of beads in electrospinning by changing an electric conductivity of a poly(vinyl alcohol) (PVA) aqueous solution and spinning conditions, such as applied voltage, distance between a tip of needle and a collector, and relative humidity. From the results of experiments done by changing the conductivity of PVA aqueous solution and spinning conditions, we found that a beads formation is suppressed at a lower electric current. Furthermore, when the electrospinnings are performed at a certain constant electric current in various spinning conditions where the applied voltage and tip-collector distance are changed so as to give the same constant electric current, resultant PVA fibers have no beads and almost the same distribution of fiber diameter. |
