“…At present, the main methods to improve the hydrophilicity of PES membranes include matrix modification and surface modification [ 9 ], such as blending [ 10 , 11 ], grafting [ 12 ], surface impregnation coating [ 13 ], surface chemical modification [ 14 ], and irradiation surface grafting [ 15 , 16 ]. Of these methods, the blending modification not only maintains the physical and mechanical properties of the PES, but also improves the hydrophilic property of PES, the water permeability and the fouling resistance of the membrane, and also improves the blood compatibility of the PES.…”

Sulfonated polyethersulfone (SPES) was used as an additive to prepare hydrophilic poly(ethersulfone) (PES) hollow fiber membranes via non-solvent assisted reverse thermally induced phase separation (RTIPS) process. The PES/SPES/N,N-dimethylacetamide (DMAc)/ polyethylene glycol 200 (PEG200) casting solutions are lower critical solution temperature (LCST) membrane forming systems. The LCST and phase separation rate increased with the increase of SPES concentrations, while the casting solutions showed shear thinning. When the membrane forming temperature was higher than the LCST, membrane formation mechanism was controlled by non-solvent assisted RTIPS process and the also membranes presented a more porous structure on the surface and a bi-continuous structure on the cross section. The membranes prepared by applying SPES present higher pure water flux than that of the pure PES membrane. The advantages of the SPES additive are reflected by the relatively high flux, good hydrophilicity and excellent mechanical properties at 0.5 wt.% SPES content.

“…[97] In a different study, 2-hydroxyethyl methacrylate (HEMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) brushes quaternized on PVDF membranes exhibited excellent antibacterial properties against S. aureus [215] and surface-initiated polymerization of PVDF with QAC had stable antifouling and bactericidal response against both E. coli and S.aureus. [209] When PVDF UF membranes were grafted with poly(N-acryloyl glycinamide) using ultraviolet (UV)-initiated radical graft polymerization, the irreversible fouling rate was just 1.2% [205] The membranes can also have enhanced bacterioresistance and foul resistance when they are tethered with small molecules.

“…The ability to functionalize and tailor the polymer surfaces using polymer brushes has been recently gaining scientific interests. In reports, PVDF, polyether ether ketone (PEEK), PES, and PSf based materials have potentially exhibited their capabilities for the growth of polymer brushes. If the functional groups in the polymer brushes are tailored to impart hydrophilicity and have an overall surface charge or have externally tethered antimicrobial compounds, then the membrane bactericidal response and antifouling characteristics will be significantly improvised ( Figure ) …”

Safe drinking water for all is a major challenge and needs critical attention, as freshwater aquifers are rapidly declining. A strategy based on addressing scarcity through membrane‐based purification and desalination can be an immediate and robust solution. The current scientific advances toward tailoring the structure and chemical properties of existing membrane materials have enabled key insights leading to new water purification alternatives. In the first part of the article, the key requirements for water decontamination addressed through state‐of‐the‐art literature on membranes are discussed. In the next part, the specific membrane modification strategies to impede bacterial growth and enhance fouling resistance are discussed, bringing in the underlying mechanisms. Finally, promising next‐generation separation techniques that are inspired by nature, inorganic and carbonaceous nanomaterial‐based membranes, layer‐by‐layer assembly, and dynamic composite membranes, are highlighted. This perspective article will help guide researchers working in this field from both industrial and academic standpoints, especially where the research is focused toward developing strategies to modify the existing solution besides finding alternative and sustainable new materials.

The oppositely charged moieties are capable of binding water molecules to form a hydration layer on material surfaces, thus prevent protein fouling 36,37 . Polyimides (PI) are classical high‐performance polymers, owing to their excellent thermal, mechanical and chemical resistance 38,39 .…”

Polysulfone ultrafiltration membranes were prepared with sulfobetaine polyimide (s‐PI) via phase inversion process, during which s‐PI migrated and enriched on the surfaces of membranes/pores due to its hydrophilic nature. Therefore, s‐PI not only enhanced surface hydrophilicity, but also acted as a pore‐forming agent. It was proved that the introduction of s‐PI effectively promoted membrane porosity and antifouling ability. Under optimized conditions, the pure water flux of blend membranes reached 220.58 L m−2 h−1 with a protein rejection ratio of 99.3%, and a flux recovery ratio of 90.86%, indicating the superior antifouling property and filtration performances of zwitterionic polymer blend membranes. Moreover, the blend membrane can stand a temperature of 90°C without degrading its separation performance. Besides excellent thermal stability, the blend membranes exhibited a distinctly advanced mechanical strength due to the addition of rigid s‐PI polymer. Overall, this study provided a facile and scalable method for the preparation of antifouling and thermally stable ultrafiltration membranes.
