Yusoff, supervisor Science Also available in printed version Electrospinning process is commonly acknowledged as a method used to fabricate variety of polymer fibers from polymer solution with diameter ranging from nanometer to micrometer. The nanofibers are produced using electrospinning process has develop in many potential applications specifically in filtration devices, tissue engineering, membranes and others. In this study, the effect of concentration of polysulfone (PSF) electrospun nanofiber are determined by electrospinning process resulting morphology of fabricated PSF surface. The result presents six different concentration (10%, 15%, 20%, 25%, 30% and 35%) that has been electrospun. It was shown that solution concentration strongly affect the fiber surface with the increasing of solution concentration. Also, we find evidence that below 5% concentration and above 35%, the fibers cannot be fabricated due to their too low and too high viscosities. In addition, above 30% of concentration, the fibers has formed in a shape of broken-like structure. It was observed that fibers formed better at 10% until 25% of PSF concentration. The interpretation of contact angle and ATR spectra data is always difficult to some extent as it does not affect by the polymer solution concentration. However, it can provide useful information on surface properties such as an ultrafiltration membrane. Hence, no apparent change on chemical properties when polymer concentration is change but only can be seen in physical properties as they come from the same materials. Experimental result lead to the hypothesis, polymer solution concentration was shown to have effects on electrospun membranes zulaihi UTM 52 p.
