“…Studies on modifications of UF membranes based on the PES-based polymer matrix have generated promising expectations in obtaining membranes modified by the incorporation of copper-based nanoparticles (Cu-NPs, CuO-NPs, Cu 2 O-NPs) or copper-based composites through the phase inversion process, in order to improve antifouling, anti-biofouling properties and filtration performance. For instance, the incorporation of Cu-NPs synthesized into PES membranes in the phase inversion process have been studied by Akar et al and Zhang et al Both studies evaluate the permeability and the anti-fouling performance in the rejection of BSA [ 49 , 55 ]. They found improvements in the hydrophilicity, the permeability performance, protein rejection ratio and antifouling effect on copper-modified membrane with respect to the neat membrane.…”

“…Other copper-based nanocomposites have also been studied for the modification of PES-based UF membranes. On the one hand, Szymański et al reported the influence of the addition of copper-modified titanate nanotubes (Cu/TNT) on the permeability, antifouling and antibacterial properties of PES membranes [ 49 ]. A notable increase in the permeability of the membranes modified by the incorporation of Cu-NPs with respect to the pristine membrane was observed.…”

“…Both strategies should be required to estimate the optimal additive concentration that has the least impact on viscosity of casting solution in order to not negatively affect the porous density of the membrane, which can be studied by modelling methods. Methodologies similar to those used on PES modification [ 49 , 52 , 53 ] have been employed by other researchers for the modification of PVDF-based UF membranes. Zhao et al worked on the incorporation of hydrophilic GO and antibacterial CuO-NPs in PVDF membranes by inversion phases process [ 54 ].…”

In the last decades, the incorporation of copper in polymeric membranes for water treatment has received greater attention, as an innovative potential solution against biofouling formation on membranes, as well as, by its ability to improve other relevant membrane properties. Copper has attractive characteristics: excellent antimicrobial activity, high natural abundance, low cost and the existence of multiple cost-effective synthesis routes for obtaining copper-based materials with tunable characteristics, which favor their incorporation into polymeric membranes. This study presents a comprehensive analysis of the progress made in the area regarding modified membranes for water treatment when incorporating copper. The notable use of copper materials (metallic and oxide nanoparticles, salts, composites, metal-polymer complexes, coordination polymers) for modifying microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), forward osmosis (FO) and reverse osmosis (RO) membranes have been identified. Antibacterial and anti-fouling effect, hydrophilicity increase, improvements of the water flux, the rejection of compounds capacity and structural membrane parameters and the reduction of concentration polarization phenomena are some outstanding properties that improved. Moreover, the study acknowledges different membrane modification approaches to incorporate copper, such as, the incorporation during the membrane synthesis process (immobilization in polymer and phase inversion) or its surface modification using physical (coating, layer by layer assembly and electrospinning) and chemical (grafting, one-pot chelating, co-deposition and mussel-inspired PDA) surface modification techniques. Thus, the advantages and limitations of these modifications and their methods with insights towards a possible industrial applicability are presented. Furthermore, when copper was incorporated into membrane matrices, the study identified relevant detrimental consequences with potential to be solved, such as formation of defects, pore block, and nanoparticles agglomeration during their fabrication. Among others, the low modification stability, the uncontrolled copper ion releasing or leaching of incorporated copper material are also identified concerns. Thus, this article offers modification strategies that allow an effective copper incorporation on these polymeric membranes and solve these hinders. The article finishes with some claims about scaling up the implementation process, including long-term performance under real conditions, feasibility of production at large scale, and assessment of environmental impact.

Based on the hydrophilicity of carboxylated carbon nanotubes (CNTs) and the paramagnetism of ferroferric oxide (Fe3O4), a CNT‐Fe3O4 nanocomplex was produced by in situ liquid phase synthesis and a magnetically induced polysulfone amide (PSA) composited CNT‐Fe3O4 ultrafiltration membrane was prepared using an immersion precipitation phase transformation with an inexpensive PSA fiber as the matrix. Fe3O4 nanoparticles were distributed evenly on the CNTs, and the obtained CNT‐Fe3O4 complex exhibited good magnetic properties. For the magnetically induced PSA composited CNT‐Fe3O4 ultrafiltration membrane, the water flux and retention rate under the magnetic field of 1450 Gs were 421.26 L/m2 h and 96.70%, respectively; porosity and pore size were 38.75% and 58.52 nm; contact angle was 39.48°; average tensile strength was 4.61 N/mm2; and weight retention rate reached 29.00% under heat treatment at 900°C. The water flux decreased by 5.40% and 39.33% after 3 weeks of acid and alkaline immersions, respectively. The inhibition zone diameter of Escherichia coli was 11 ± 0.24 mm, and that of Staphylococcus aureus was 11 ± 0.35 mm. The magnetically induced PSA composited CNT‐Fe3O4 ultrafiltration membrane demonstrated stronger electronegativity, smaller average roughness, higher flux recovery rate value, and lower irreversible flux recovery rate value.

In the presented studies it was hypothesized that the modification of a polymeric membrane with a pore former and a hybrid nanomaterial composed of titanate nanotubes with deposited Ag nanoparticles (Ag-TNTs NPs) can protect the membrane from the microbial growth, and thus enhance its resistance to biofouling. Polyethersulfone (PES) membranes were prepared by the wet phase inversion, and polyvinylpyrrolidone (PVP) and poly(ethylene glycol) (PEG) were used as pore formers. The membranes were characterized in terms of morphology, topography, permeability, separation characteristics, and anti-(bio)fouling properties as well as antibacterial activity. The membranes modified with porogens and Ag-TNTs revealed improved hydrophilicity and water permeability compared to the unmodified membrane, from 58 to 66%. Moreover, the improvement in rejection of model dextrans and PEG upon application of the NPs was found. However, the use of PVP or PEG had a negative influence on the resistance to fouling by bovine serum albumin, i.e., ca. 35% of decline of permeate flux was noticed after 2 h of ultrafiltration of BSA. On the contrary, both porogens and NPs contributed to biofouling mitigation. The introduction of pore formers had a positive effect on the inhibition of Escherichia coli growth by the membrane containing Ag-TNTs. The log reduction of bacteria varied from 3.17 to 3.3 in case of stirred and filtration system.
