      Abstract:

     

        In this study, polysulfonn nanofibers were electrospun and     effects of electrospinning parameters including applied voltage     and tip-to-collector distance on the morphology of electrospun     PSf nanofibers were investigated by SEM. SEM images of     electrospun nanofibers showed that morphology and diameter of     the nanofibres were mainly affected by applied voltage. Fourier     transform infrared spectrometer and     thermo-gravimetric/differential scanning calorimeter analysis     were used for investigate the chemical and thermal properties     of PSf nanofibers, respectively. The applied voltage and     tip-to-collector distance were all shown to have varying     effects on fiber diameter and fiber uniformity. Increasing the     applied voltage results in increases the surface charge of the     jet and helps to reduce the frequency of occurrence of beads.     It has shown that tip-to-collector distance directly affects     spinnability and fiber diameter and at very low distance (5cm)     droplets were formed due to the electro-spraying.
