Abstract
In this study, poly (vinyl alcohol) / chitosan blend nanofibers were synthesized by electrospinning process in different polyvinyl alcohol and chitosan weight ratios. The nanofibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and X-ray diffraction (XRD). SEM images showed that, 50:50 poly vinyl alcohol/chitosan blend was the ideal ratio for producing beadless nanofiber. The average diameter of the beadless nanofiber was found to be 123 nm. FTIR and XRD results demonstrated the presence of intermolecular hydrogen bonding between the molecules of poly vinyl alcohol and chitosan.
