Online Measurement of Electrospinning Jet Velocity of Polyvinyl Alcohol

S. J. Choi, C. S. Kong, D. H. Han and H. S. Kim

Abstract

Electrospinning is a fascinating technology for producing nanoscale fibers. In this study, jet velocities were investigated for the full jet range using microparticles as tracers. Significant differences were observed in the jet velocities as a function of the measuring position and direction. This suggests that the jets drive toward the collector and undergo jet separation after forming jet entanglements. The visual evidence confirmed the jet elongation data.
