Advancements in Mixed-Matrix Membranes for Various Separation Applications: State of the Art and Future Prospects

Membranes, Год журнала: 2024, Номер 14(11), С. 224 - 224

Опубликована: Окт. 25, 2024

Integrating nanomaterials into membranes has revolutionized selective transport processes, offering enhanced properties and functionalities. Mixed-matrix (MMMs) are nanocomposite (NCMs) that incorporate inorganic nanoparticles (NPs) organic polymeric matrices, augmenting mechanical strength, thermal stability, separation performance, antifouling characteristics. Various synthesis methods, like phase inversion, layer-by-layer assembly, electrospinning, surface modification, enable the production of tailored MMMs. A trade-off exists between selectivity flux in pristine polymer or plain ceramic/zeolite membranes. In contrast, MMMs, NPs exert a profound influence on membrane enhancing both permeability simultaneously, besides exhibiting antibacterial efficacy. Membranes reported this work find application diverse notably niche membrane-based applications, by addressing challenges such as fouling degradation, low flux, selectivity, poor rejection properties. This review comprehensively surveys recent advances nanoparticle-integrated across various fields water purification, heavy metal removal, dye gaseous separation, pervaporation (PV), fuel cells (FC), desalination. Efforts have been made to underscore role advancing environmental remediation efforts drinking quality concerns through interesting case studies literature.

Synergistic Construction of Sub-Nanometer Channel Membranes through MOF–Polymer Composites: Strategies and Nanofiltration Applications

Polymers, Год журнала: 2024, Номер 16(12), С. 1653 - 1653

Опубликована: Июнь 11, 2024

The selective separation of small molecules at the sub-nanometer scale has broad application prospects in field, such as energy, catalysis, and separation. Conventional polymeric membrane materials (e.g., nanofiltration membranes) for separations face challenges, inhomogeneous channel sizes unstable pore structures. Combining polymers with metal–organic frameworks (MOFs), which possess uniform intrinsic structures, may overcome this limitation. This combination resulted three distinct types membranes: MOF polycrystalline membranes, mixed-matrix membranes (MMMs), thin-film nanocomposite (TFN) membranes. However, their effectiveness is hindered by limited regulation surface properties growth MOFs poor interfacial compatibility. main issues preparing are uncontrollable adhesion between substrate. Here, could serve a simple precise tool regulating functionalities while enhancing to For primary challenge compatibility MOFs. Strategies mutual modification enhance introduced. TFN challenges include difficulty controlling polymer layer performance limitations caused “trade-off” effect. can modulate formation process establish transport channels within matrix effect limitations. review focuses on mechanisms synergistic construction polymer–MOF structure–nanofiltration relationships, have not been sufficiently addressed past.

Development and Characterization of Silicotungstic Acid-loaded Sodium Polymeric Composite Membranes for Pervaporation Applications

Asian Journal of Chemistry, Год журнала: 2025, Номер 37(4), С. 865 - 872

Опубликована: Март 29, 2025

Efforts have been focused on the membrane synthesis, specifically enhancing properties through incorporation of zeolites into a polymer matrix. This study emphasizes development sodium carboxymethyl cellulose (NaCMC)/poly(vinylpyrrolidone-co-vinyl acetate) [P(Vp-co-VAc)] matrix composite membranes via solution casting method, incorporating varying amounts silicotungstic acid (STA) (5, 10, and 15 wt.%) for pervaporation dehydration water-isopropanol mixture. The developed films were characterized by FTIR, DSC, TGA, XRD SEM techniques. Among all STA-loaded membranes, optimum performance was observed in MSTA15 membrane, which had flux equal to 0.533 kg/m2 h at 35 ºC separation factor 118.52 40 wt.% feed composition. exhibits good hydrophilic nature molecular sieve effect. Furthermore, showed improved compared pristine membranes. These results this suggested that act as prominent materials effective isopropanol.
