“…In order to surmount the permeability versus selectivity shortcoming, Junaidi et al and Liu et al incorporated zeolites within PS [7,8], while Ahn and coworkers used silica nanoparticles [9]. To reduce fouling effects, Nair et al chose CaCO 3 nanoparticles [5], whereas Mollahoseini et al opted for silver nanoparticles [10]. Zhang et al suggested that 2-hydroxyethyl methacrylate-coated TiO 2 nanoparticles, organic and inorganic combined filler, also promote hydrophobicity and therefore antifouling features [11].…”

“…It is reported by Hamid et al which using TiO2 in PVDF membrane that this inorganic additives was found to improve membrane fouling properties 3 . Other paper reported by Yuliwati et al found that similar materials which is TiO2 at 2 wt% concentration contributed to increase fouling properties of membrane due to increase in surface roughness 16 . Arash et al found that 2 wt% of silver improved water permeability and rejection of membrane eventhough a dense crossection of membrane form 16 .…”

The effects of different zinc oxide concentration on morphology, contact angle, surface roughness and rejection towards humic acid in polysulfone membrane were investigated. Flatsheet ultrafiltration membrane were prepared by using polysulfone as based polymer, polyethylene glycol as pore forming agent, zinc oxide as manipulated additive and TAP as compatibilizer. In this study, N, methyl-2-pyrrolidone were used as solvent and water as non solvent. The membrane were prepared via phase inversion method. Results showed that pure water flux was enhanced by the presence of zinc oxide up to 1 wt% and tend to decrease beyond this concentration. The increased pure water flux was attributed to the increase in hydrophilicity and surface roughness of membrane according to contact angle and AFM measurement. The rejection test with humic acid as solute revealed that by increasing zinc oxide concentration, rejection increases up to 98% at 2 wt% of zinc oxide. Therefore polysulfone/zinc oxide in this study can provide potential application for river water treatment which consist high humic acid concentration.

“…Engineering polymers of polysulfone (PSF) groups, [50][51][52] polycarbonates, 53 poly(aryl ketones), and polyimides (PI) [54][55][56][57][58][59] have demonstrated specifications like the applied material in the composite membranes. Among the polymeric precursors in the preparation of composite membranes, polysulfones and polyimides are the most fascinating because of their excellent properties, such as high productivity and efficiency of separation, high thermal and chemical stability, high mechanical resistance, and ease of preparation.…”

The development of desirable chemical structures and properties in nanocomposite membranes involve steps that need to be carefully designed and controlled. This study investigates the effect of adding multiwalled nanotubes (MWNT) on a Kapton-polysulfone composite membrane on the separation of various gas pairs. Data from Fourier transform infrared spectroscopy and scanning electron microscopy confirm that some studies on the Kapton-polysulfone blends are miscible on the molecular level. In fact, the results indicate that the chemical structure of the blend components, the Kapton-polysulfone blend compositions, and the carbon nanotubes play important roles in the transport properties of the resulting membranes. The results of gas permeability tests for the synthesized membranes specify that using a higher percentage of polysulfone (PSF) in blends resulted in membranes with higher ideal selectivity and permeability. Although the addition of nanotubes can increase the permeability of gases, it decreases gas pair selectivity. Furthermore, these outcomes suggest that Kapton-PSF membranes with higher PSF are special candidates for CO 2 /CH 4 separation compared to CO 2 /N 2 and O 2 /N 2 separation. High CH 4 , CO 2 , N 2 , and O 2 permeabilities of 0.35, 6.2, 0.34, and 1.15 bar, respectively, are obtained for the developed Kapton-PSF membranes (25/75%) with the highest percentage of carbon nanotubes (8%), whose values are the highest among all the resultant membranes.
