“…Bacterial adhesion has been found to decrease significantly by making the surface more hydrophilic, negatively charged, and/or smooth. Membranes with an anti-adhesive surface have been reported, including surface coating/grafting of hydrophilic monomers, zwitterionic/amphiphilic polymers, and incorporation of nanomaterials [ 64 , 65 ]. The polymer with hydrophilic groups facilitates the formation of a compact hydration layer through electrostatic interactions and hydrogen bonds, which can sufficiently prevent macromolecules and microbes from adsorption onto the membrane surface, reducing the irreversible membrane fouling [ 66 , 67 ].…”

Polymeric membranes, such as polyamide thin film composite membranes, have gained increasing popularity in wastewater treatment, seawater desalination, as well as the purification and concentration of chemicals for their high salt-rejection and water flux properties. Membrane biofouling originates from the attachment or deposition of organic macromolecules/microorganisms and leads to an increased operating pressure and shortened service life and has greatly limited the application of polymeric membranes. Over the past few years, numerous strategies and materials were developed with the aim to control membrane biofouling. In this review, the formation process, influence factors, and consequences of membrane biofouling are systematically summarized. Additionally, the specific strategies for mitigating membrane biofouling including anchoring of hydrophilic monomers, the incorporation of inorganic antimicrobial nanoparticles, coating/grafting of cationic bactericidal polymers, and the design of multifunctional material integrated multiple anti-biofouling mechanisms, are highlighted. Finally, perspectives on the challenges and opportunities in anti-biofouling polymeric membranes are shared, shedding light on the development of even better anti-biofouling materials in near future.

“…116 Furthermore, Li et al fabricated a zwitterionic membrane with improved flux and outstanding antifouling performance tested with BSA, SA and SDS (sodium dodecyl sulfate). 104 The fouling resistance is attributed to the improved hydrophilicity and increased negative surface charge which led to stronger repulsion toward the foulants. The stability of membrane was ensured throughout a 64 h continuous filtration where it had a constant permeability while NaCl rejection slightly increased from 96.5 to 98.5%.…”

Numerous materials have been employed in the surface modification of membranes, including different polymers and nanomaterials over the years. The pernicious challenges of membrane separation include the trade-off between water permeability and solute rejection as well as fouling when it is tested under liquid conditions. Zwitterionic polymers have attracted wide interest due to their unique properties of containing both cationic and anionic groups while maintaining electroneutrality and high hydrophilicity. These zwitterionic polymers have been utilized as coating materials or grafted layers not only on the surfaces of porous membranes but also as thin film composite membranes. To illustrate, the membranes modified with this class of materials are capable of resisting foulants through two distinct mechanisms, which are the hydration layer formation and steric repulsion effect, showcasing their unique chemical properties. To bridge the gaps of the recent development of zwitterionic membranes and their relationships with foulants for targeted separation such as ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), this critical review will first fundamentally classify the fouling into four categories according to their characteristics and fouling mechanisms, namely, inorganic foulants, nonmigratory foulants, spreadable foulants, and proliferative foulants. The antifouling strategies which are active antifouling and passive antifouling (e.g., fouling resistance and fouling release) will be summarized. Apart from that, the chemistry, morphology, and modification approaches of zwitterionic membranes including surface coating, surface grafting, and physical blending on targeted applications as well as the separation performance of the state-of-the-art membranes will be presented in detail. Lastly, the summary, outlook of major challenges and opportunities of the zwitterionic materials will be highlighted. It is anticipated that this review can generate a pathway to facilitate the next generation of zwitterionicbased membranes with superior separation performance for specific separation.

“…The support was then immersed in ethanol for 10 min to remove any unreacted polydopamine and then rinsed with purified water . A PA active layer was formed on the nanofiber supports by interfacial polymerization as reported previously. , 1.5 wt % of MPD was dissolved in purified water and 0.05 wt % of TMC was dissolved in n -hexane respectively, and degassed by ultrasonication. A nanofiber support was held within a rubber gasket frame and binder clips, then MPD solution was poured into the frame for 5 min.…”

“…RO membranes are typically prepared as a thin-film composite consisting of three layers; a nonwoven fabric for mechanical strength, a microporous supporting layer, and an ultrathin polyamide (PA) active layer on the top surface for separation. − Increasing the water flux of typical thin-film composite (TFC) membranes by reducing the thickness of their selective layers has been a focal subject in RO membrane research, and membranes with extremely thin PA selective layers (∼100 nm) have been fabricated at industrial scale . However, very little research has been done to engineer the microporous supporting layer.…”

A novel membrane structure comprised of cross-hatched electrospun nanofibers is developed. We illustrate that this novel structure allows for much higher water permeability when used as a support for reverse osmosis thin-film composite membranes. Reinforcement and lamination of the aligned nanofibres generates mechanically robust structures that retain very high porosity and low tortuosity when applied to high pressure seawater desalination operations. The cross-hatched nanofibre layers support the polyamide active layer firmly and reduce resistance to water flow due to the high porosity, low tortuosity, high mechanical strength and minimal thickness of the structures. The nanofibre composite membrane gives a water flux significantly greater than when a traditional support layer is used, at 99 ± 5 m -2 h -1 with NaCl rejection of 98.7 % at 15.5 bar.
