“…In this work, non-solvent-induced phase separation (NIPS), a simple, inexpensive, and scalable method commonly used to make diaphragm and ultrafiltration membrane ( Luque-Alled et al., 2020 ; Li et al., 2014 ), is applied to make cooling coatings for daytime passive radiation cooling. The porous polymers start from the preparation of a precursor solution of P(VdF-HFP) (polymer) and water (non-solvent) in dimethylformamide (DMF, solvent).…”

“…Severe fouling in PES-based membranes from hydrophobic reactions of membrane surface interactions with foulants and the concomitant membrane flux decline has been widely reported [ 12 , 24 , 25 , 37 ]. Membrane fouling leads to degeneration of the selectivity and permeability of the membrane during protein separation and reduces the membrane lifetime.…”

“…Figure 9 shows that incorporating PSN into the PES membrane lowered the R ir values from 51.39% in the pristine membrane to 20.27% in the M 4 (0.50 wt %) membrane. In practice, this implies a reduction in the number of cleaning cycles (lower cleaning cost) required for composite membranes having a lower R ir [ 37 ]. The R r values of the membranes incorporated with PSN were greater than those of the pristine membrane, signifying an enhanced effacing of foulants from the outer layer of the composite membrane through a mere hydraulic disinfection operation [ 38 ].…”

Antifouling Polyethersulfone-Petrol Soot Nanoparticles Composite Ultrafiltration Membrane for Dye Removal in Wastewater

Engineered nanoparticles are known to boost membrane performance in membrane technology. Hitherto, tunable properties that lead to improved hydrophilicity due to increased surface oxygen functionalities upon oxidation of petrol soot have not been fully exploited in membrane filtration technology. Herein, the integration of oxidized petrol soot nanoparticles (PSN) into polyethersulfone ultrafiltration membranes produced via phase inversion technique for dye removal in wastewater is reported. The nanoparticles, as well as the composite membranes, were characterized with diverse physicochemical methods, particularly TEM, SEM, BET, AFM, contact angle, etc. The effect of varying the ratio of PSN (0.05–1.0 wt %) on the properties of the composite membrane was evaluated. The composite membranes displayed increased hydrophilicity, enhanced pure water flux, and antifouling properties relative to the pristine membrane. For example, the obtained pure water flux increased from 130 L·m−2·h−1 for base membrane to 265 L·m−2·h−1 for the best composite membrane (M4). The best flux recovery ratio (FRR) observed for the membranes containing PSN was ca. 80% in contrast to 49% obtained with the pristine membrane indicative of the positive influence of PSN on membrane antifouling behavior. Furthermore, the PSN composite membranes displayed relatively selective anionic dye rejection of ˃95% for Congo red and between 50–71% for methyl orange compared with 42–96% rejection obtained for cationic methylene blue dye with increasing PSN content. The successful fabrication of polyethersulfone–PSN composite membranes by a simple blending process opens a novel route for the preparation of economical, functional, and scalable water purification membranes capable of addressing the complex issue of water remediation of organic azo dyes.

“…[4][5][6][7] Sulfone-containing polymers have been commonly used to prepare nanofiltration (NF) and ultrafiltration and are used in water applications. [8] The main limitation of using this technology is their fouling caused by unfavorable adsorption and accumulation of foulants on the membrane interface or within the pores. [9,10] Surface characteristics such as hydrophilicity, charges, and the roughness are the key factors that cause fouling.…”

The selection of polyethersulfone/polyvinylpyrrolidone films for industrial application using the multiple‐criteria decision‐making approach

The polyethersulfone (PES)-based composite polymers have been extensively studied for many years as the core of various scientific activities, such as fuel cell production, water treatment, reverse osmosis, ultrafiltration, nanofiltration, and gas separation, which represent a significant field of research for several applications. In the present study, PES and polyvinylpyrrolidone-coated magnetic coreshell nanoparticles (NPs) are synthesized. Following this, a range of these NPs and PES blend polymers are prepared. Then, analyzing methods are used for identification and characterization of a variety of these samples. Since some properties of the samples have been improved, and others are attenuated, the best composition could not be selected from the samples without a logical process. To do so, a multiple-criteria decision-making (MCDM) technique that considers all the desired parameters is utilized. A MCDM algorithm is applied to create a ranking of alternative properties from the best to the worst, alongside mathematical calculations which accounts for the relative importance of the criteria. Results have shown that PES film with 15% of polymer-coated NPs presents the best performance based on the desired properties.
