Abstract

The exploitation of technologies based on electro spinning have been limited due to poor understanding of the process and consequent limitation in process control, productivity and reproducibility. To control the effect of the environmental parameter, which is one of important electro spinning parameters, the vacuum process was introduced because the magnitude of electric field in vacuum is not limited by the low dielectric breakdown strength of air. For this study, PCL dissolved in a mixture of N,N-dimethylformamide (DMF) and methylene chloride (MC) was electrospun as a form of nonwoven mats consisting of nano-sized fibers under vacuum and they have been analyzed using SEM and DSC. The PCL nonwoven mats via electrospinning under vacuum showed the characteristic spinning behavior observed at atmospheric pressure. In addition, results obtained from tensile test showed that PCL nonwoven mats via electro­spinning under vacuum have better mechanical properties than those prepared at atmospheric pressure.
