Effect of Different Factors on Falling Process of Melt Electrospinning Jet

Abstract:

The falling process of melt electrospinning jet is different from those of solution electrospinning in which there is apparent solvent volatilization. In order to study the factors influencing on the forming process of fibers in melt electrospinning, dropping process of fibers is recorded and analyzed via high speed video camera in the article. Results showed that there was an optimal spinning temperature for melt electrospinning of the polymer; the greater the voltage was, the more obvious stretching action on jet was. However, the voltage did not exceed a certain value, because there was a spinnable voltage limit corresponding to every receiving distance. When the spinning distance was generally short, the jet swinging radius decreased with increasing spinning distance; when the spinning distance was long, the jet was subject to the influence of the environment temperature easily. The changes of viscosity had dominant influence on the motion of jet.
