چکیده

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.
