Self-assembly of TiO2 nanoparticles around the pores of PES ultrafiltration membrane for mitigating organic fouling

Ag modified g-C3N4 composite entrapped PES UF membrane with visible-light-driven photocatalytic antifouling performance

“…The accelerated demixing process may facilitate the fully development of the nger-like micro voids in nanocomposite membranes. 28 It is also believed that if the nanoparticles had higher affinity to non-solvent, elongated macrovoids could appear due to the higher solvent/non-solvent exchange rate. 29 In this study, the hydrophilic group such as -NH as shown in Fig.…”

Photoactive Hybrid Film Photocatalyst of Polyethersulfone-ZnO for the Degradation of Methyl Orange Dye: Kinetic Study and Operational Parameters

“…The generation of a porous substructure with finger-like microvoids could be attributed to the instantaneous phase inversion that took place during the preparation of the films [25,26]. The porosity of the films also increased with increased ZnO loading from 0.04% (pristine PES) to 0.23% (PZ-17).…”

Enhanced Cu(II) rejection and fouling reduction through fabrication of PEG-PES nanocomposite ultrafiltration membrane with PEG-coated cobalt doped iron oxide nanoparticle

“…BSA was chosen as the model foulant to evaluate the antifouling properties of the modified membrane toward the organic foulant [28]. The filtration performance of the membranes was measured in the same cross flow filtration cell.…”

“…Molecular weight cut off (MWCO) of a membrane is defined as the size of the membrane where 90% of solute can be rejected by the membrane [28] and is determined from the solute separation curves as depicted in Supplementary Data 1 and summarized in Table 1. An increase in nanoparticles composition had reduce the MWCO of the membrane, owed to the suppression of marcovoids formation, however when the coated PEG concentration increase, the MWCO are found to increase.…”
