“…This includes (i) interfacial polymerization (IP), whereby CDs are incorporated in a thin lm composite (TFC) to obtain a thin lm nanocomposite (TFNC) membrane; (ii) phase separation where CDs are blended with polymers followed by phase separation techniques to obtain mixed matrix membranes (MMMs); (iii) coating where CDs are coated onto the substrate by various means such as ltration, immersion, spin-coating, layer-by-layer (L-b-L) selfassembly, casting, graing, and in situ synthesis. 56,57 Each method offers unique advantages, and the choice of preparation method ultimately depends on the desired properties and application of the nanocomposite membrane. The extensive collection of data on the fabrication of nanocomposite membranes involving CDs and some of their properties for separation applications are presented in four tables.…”

“…A significant amount of work related to the development of membranes for liquid separation processes have been published in the past 10 years, indicating the importance of this topic to industries and communities. Membrane modification through the introduction of nanomaterials is one of the most extensively reviewed topics in view of the effectiveness of this strategy in tailoring the physico-chemical properties of membranes [ 37 , 38 , 39 , 40 , 41 ]. Significant efforts have been made in developing nanocomposite membranes using metal oxides including TiO 2 , which is well-known for its low cost, abundancy, high chemical stability, and nontoxicity to the environment and humans.…”

Membrane technology has become increasingly popular and important for separation processes in industries, as well as for desalination and wastewater treatment. Over the last decade, the merger of nanotechnology and membrane technology in the development of nanocomposite membranes has emerged as a rapidly expanding research area. The key motivation driving the development of nanocomposite membranes is the pursuit of high-performance liquid separation membranes that can address the bottlenecks of conventionally used polymeric membranes. Nanostructured materials in the form of zero to three-dimensions exhibit unique dimension-dependent morphology and topology that have triggered considerable attention in various fields. While the surface hydrophilicity, antibacterial, and photocatalytic properties of TiO2 are particularly attractive for liquid separation membranes, the geometry-dependent properties of the nanocomposite membrane can be further fine-tuned by selecting the nanostructures with the right dimension. This review aims to provide an overview and comments on the state-of-the-art modifications of liquid separation membrane using TiO2 as a classical example of multidimensional nanomaterials. The performances of TiO2-incorporated nanocomposite membranes are discussed with attention placed on the special features rendered by their structures and dimensions. The innovations and breakthroughs made in the synthesis and modifications of structure-controlled TiO2 and its composites have enabled fascinating and advantageous properties for the development of high-performance nanocomposite membranes for liquid separation.

“…Reviews on TFN membranes have recently been published by Bhaskar et al [ 21 ], Kumar et al [ 22 ], Liao et al [ 23 ], Kadhom et al [ 24 ], Krishnan et al [ 25 ], Zhao et al [ 26 ], and Li et al [ 27 ]. Comprehensive reviews were presented on the use of nanofillers as quantum dots [ 28 ], metal–organic frameworks (MOFs) [ 29 , 30 ], organic-based nanomaterials [ 31 ], nanomaterial positions and dimensions [ 32 ], and on TFN membranes with an interlayered structure [ 33 , 34 ], for RO desalination [ 35 ], and for pervaporation applications [ 36 ], loose nanofiltration [ 37 ], thermal stability [ 38 ], and surface characterization using contact angle techniques [ 39 ]. Additionally, numerous advancements have been made in the methodology of embedding nanofillers in TFNs.…”

View full text Add to dashboard Cite

Thin-film nanocomposite (TFN) membranes have been widely investigated for water treatment applications due to their promising performance in terms of flux, salt rejection, and their antifouling properties. This review article provides an overview of the TFN membrane characterization and performance. It presents different characterization techniques that have been used to analyze these membranes and the nanofillers within them. The techniques comprise structural and elemental analysis, surface and morphology analysis, compositional analysis, and mechanical properties. Additionally, the fundamentals of membrane preparation are also presented, together with a classification of nanofillers that have been used so far. The potential of TFN membranes to address water scarcity and pollution challenges is significant. This review also lists examples of effective TFN membrane applications for water treatment. These include enhanced flux, enhanced salt rejection, antifouling, chlorine resistance, antimicrobial properties, thermal stability, and dye removal. The article concludes with a synopsis of the current status of TFN membranes and future perspectives.
