Characterization and antifouling performance of negatively charged PES/mesoporous silica ultrafiltration membrane for raw water filtration

Preparation and characterization of hydrophilic and antifouling poly(ether sulfone) ultrafiltration membranes modified with Zn–Al layered double hydroxides

“…11 Therefore, various methods to improve the antifouling properties of PES membranes have been studied by researchers. For example, studies on interfacial polymerization, 12,13 surface graft polymerization, 14 ultraviolet irradiation, 15 coating, 16 and blending 5,17,18 have been carried out with different membrane modifiers. The blending of inorganic materials into membranes as modifiers has been one focus area of this research.…”

“…[1][2][3][4] Therein, the use of ultrafiltration membranes, in which the membrane material properties are vital, is one of the most popular techniques. 5 Poly(ether sulfone) (PES) has gained tremendous attention as a promising polymeric membrane material because of its outstanding chemical and physical properties (e.g., thermal stability, pressure, and heat resistance). 6,7 However, the inherent hydrophobicity of PES and the pressuredriven properties of ultrafiltration cause the poor antifouling properties of the ultrafiltration process with PES membranes.…”

Graphene oxide polypiperazine-amide nanofiltration membrane for improving flux and anti-fouling in water purification

“…52 Thus, a thin water layer may be formed between the hydrophilic surface and water solution via hydrogen bonds, 10 and largely helped to retard the absorption of hydrophobic pollutants on the membrane surface and reduce the membrane fouling. 67,68 Moreover, a smoother of M3 membrane surface (Table 5) could also contribute to improve the anti-fouling property.…”

Ultrafiltration Mixed Matrix Membranes Based on Mesoporous Silica (MCM-41, HMS)Embedded in Polysulfone

“…One way to overcome this drawback may be achieved by improving of hydrophilicity of membranes by blending the polymeric matrix with porous or non-porou inorganic fillers [6][7][8][9][10][11]. Among numerous inorganic fillers, silica, SiO 2 , in form of nonporous (nano)particles or as mesoporous material, is extensively used due to its facile preparation, mild reactivity and wellknown chemical properties [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Numerous examples of hybrid membranes incorporated with solid silica particles (SiO 2 ) have been reported and demonstrated that the addition of SiO 2 into polymer film is beneficial to membrane separation performance either in terms of membrane flux or selectivity [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

“…Compared to solid silica particles, mesoporous silicas have special properties such as higher specific surface area, porosity, tunable pore structures with inner surface easy to functionalize, and the porous nature of the inorganic fillers gives them a high water permeability through mixed matrix membrane filler-polymer. Mesoporous MCM-41 materials have been incorporated in polyethersulfone (PES) [20] and the resulted membranes (with 2% wt MCM-41) exhibited excellent hydrophilicity, water permeability and good antifouling performance, efficient in raw water purification experiments [14,20]; in polysulfone (Psf) to enhance the gas permeability (N 2 , O 2 , CH 4 and CO 2 ) [21].…”
