Abstract: | Electrospinning is a process of electrostatic fiber formation which uses electrical forces to produce polymer nanofibers from
polymer solution. The electrospinning system consists of a syringe feeder system, a collector system, and a high power supplier.
The important parameters in the morphology of electrospun polystyrene fibers are concentration, applied voltage, and solvent
properties. Higher concentrations of the polymer solution form thicker fibers and fewer beads. When the concentration is 7
wt%, electrospun fibers have an average diameter of 340 nm, but as the concentration of PS increases to 17 wt%, the fiber
diameter gradually thickens to 3,610 nm. The fiber morphology under different solvent mixture ratios and solvent mixtures
has also been studied. |
