Abstract
Uniform and beadless PVA hollow nanofibers with a mean shell thickness of less than 100 nm were successfully prepared by one-pot coaxial electrospinning technique. The morphology and diameter of nanofibers were characterized by scanning electron microscopy (SEM). The micrographs indicated that the air flow rate could control the morphology of electrospun hollow nanofibers. Also, they showed that nanofiber diameter increased with increasing air flow rate. To obtain PVA hollow nanofibers, the ratio of air flow rate to the solution feed rate was adjusted at 75.
