“…From the table, as the PSf concentration increases, the fiber diameter of NF 9 decreases and then increases again with NF 10. According to Zahari et al, 47 the concentration of the polymer solution does not significantly affect the average fiber diameter. A particular property of the technology that can be understood during electrospinning is that the formation of nanofibers is random and invisible to the naked eye.…”

“…This might be due to the increased hydrophobicity of the membrane as supported by increasing value of water contact angle. This phenomenon is thought to be due to the fact that there is almost no hydrogen bond interaction at the boundary layer between the NFs membrane interface and water 47,50 . Therefore, unlike other hydrophilic membranes, the membrane does not absorb water.…”

Hence, the NF 9 nanofiber membrane has been chosen due to improved hydrophilicity and higher water flux of membrane, 98.93 and 70.27 L/m 2 h bar.…”

Hydrophilicity is one of the ideal properties for water treatment membrane. In addition, higher surface area with a porous structure results in extraordinary permeability and selectivity, thus making it a good candidate for water permeability. This study used iron oxide nanoparticles (IONPs) as polysulfone (PSf) membrane nanofillers to enhance the physicochemical properties. Nanofiber membranes were characterized in terms of morphology, wettability, and pure water permeability (PWP). The concentration of IONPs was varied from 0.5% to 2.0% (w/v). From the scanning electron microscope images, all produced membranes were smooth and contain bead-free nanofibers. The produced nanofiber membrane with 1% (w/v) of IONPs concentration was found to be optimum since it had the highest porosity, lower contact angle, and desirable fiber thickness and diameter. In order to find the best PSf solution concentration, the loadings of PSf were varied from 18% to 27% (w/v). The PSf/IONPs with 25% (w/v) provided the best results in terms of fiber thickness and diameter, porosity and morphology. The contact angle also confirmed that in the presence of IONPs, the nanofiber structure produced with 25% PSf was less hydrophobic and had the highest PWP (70.27 L/m 2 h bar).

“…The electrospinning method produced nanofibers in the range of micrometers until nanometer scale [3][4][5] . These small fibers are potentially using for many applications, such as membrane of filtration and composite materials [6][7][8][9][10] . Beside the size of the fibers, the electrospinning produces high surface area of threads.…”

<p class="IJASEITAbtract">The electric field distribution of the Neddle-Plate (NP) electrospinning set up has reported due to the simple classical electrodynamics solutions. The charge is assumed to distribute uniformly in the needle (nozzle) and the collector (plate). The electric field has an influence only in the early stage of the electrospinning process. The electric field and the viscosity of the jet fluid have caused the bending of the straight jet. The high viscosity of the fluid can preserve the straight jet length much longer. The electric field gives the initial angular momentum of the jet due to the whipping motion of the jet. For the area away from the nozzle, the electric does not influence the whipping motion. Then the whipping motion solely due to the influence from the charge repulsion of the jet fluid and the evaporation of the solvent.</p>

This research investigates the solution parameters, i.e., polymer concentration and addition of manganese (IV) oxide (MnO2) nanoparticles, for the fabrication of polysulfone (PSF) fibers via electrospinning. Initially, PSF was dissolved in N,N-dimethylformamide (DMF) solvent and electrospun fibers with different morphologies were obtained using the range of PSF concentration of 10% (w/v) to 25% (w/v). Subsequently, PSF with the concentration of 20% (w/v) (denoted as PSF(20%)) was chosen to blend with 0.2% (w/v) of MnO2 as it gave the most stable electrospinnability and uniform fiber diameter. The fabricated electrospun PSF(20%) and PSF(20%)-MnO2 fibrous membranes were characterized to determine the morphology, wettability property, zeta potential, and tensile strength. The presence of MnO2 improved tensile strength as it reduced the fiber diameter that eventually made a more compact fiber mat membrane. The results of contact angle confirmed that the fabricated fiber exhibited more hydrophobic property in the presence of MnO2 nanoparticles. Thus, it reduced the pure water flux of PSF fiber membrane. The more hydrophobic nature of the proposed nanofiber might be useful in enhancing the application of PSF fiber in oil-water separation process.
