“…Moreover, construction of interlayer/sacrificial layer (e.g. nanoparticle, polyelectrolyte and mussel-inspired coating) on the substrate can also effectively regulate the surface pore size and hydrophilicity; thus, facilitating the uniform IP process [34]. Using polydopamine as an interlayer, Yang et al prepared a PA membrane with improved hydrophilicity, increased crosslinking degree and narrower pore distribution, which showed a high permeability (14.8 Lm -2 h -1 bar -1 ) and a desirable antibiotic/monovalent ion selectivity [35].…”

Nanofiltration (NF) with advantages of high efficiency and low‐cost has attracted increasing attentions in bio‐separation. However, the large‐scale application is limited by the inferior molecular selectivity, low chemical stability and serious membrane fouling. Many efforts, thus, have been devoted in NF materials design for specific applications to enhance the separation efficiency of bio‐products and increase membrane life‐time, as well as reduce the operating cost. This review summarized the recent progress of NF applications in bio‐separation, discussed various demands for NF membrane in the bio‐products purification and corresponding material innovations, finally proposed several practical suggestions for future research, which provided directions and guidance toward further product development and process industrialization.

“…After a 20 h fouling test, the fouling resistance of all the TFN membranes incorporated with the CQDs was significantly enhanced. Yang et al [81] prepared a CQD/TFC membrane for the valorization of biogas slurry. In this membrane, the CQDs were deposited on a PES substrate and then a thin PA layer was synthesized on it through IP.…”

Membrane technology provides a reliable and powerful solution to combat the global water crisis by producing fresh water through sustainable desalination. However, the decline in system performance due to membrane biofouling is a limitation and significant efforts have been made to explore fouling control mechanisms and develop simple methods to inhibit or eliminate membrane fouling. Nanotechnology has increased the number of options for the development of antibiofouling membranes by incorporating nanoparticles within the polyamide layer to produce a thin‐film nanocomposite (TFN) structure. This review presents recent advances in the preparation of antifouling TFN membranes and incorporation of different nanoparticles into the design. The review also discusses the strategies and mechanisms for reducing membrane fouling and proposes a future outlook for the field.

“…Recently, a TFC membrane with 10-nm selective layer thickness with ultrafast solvent permeance was reported [ 56 ]. In the TFC membrane, the selective layer mostly governs the separation performance, and the support layer provides the necessary mechanical support and handleability [ 2 ]. The performance of TFC membranes can be affected significantly by the support layer, and thus, optimization of the support layer morphology is also important.…”

“…Among different types of membrane technologies, organic solvent nanofiltration (OSN) is a membrane process with capabilities to discriminate nanometer-sized molecules in organic solvents [ 1 ]. Different from ultrafiltration and reverse osmosis, nanofiltration membranes exhibit pore size distributions of 0.5–2 nm [ 2 ]. OSN has been recognized as a sustainable separation platform with low energy consumption [ 3 ] and, also, as a platform to achieve process intensification via reaction-separation convergence [ 4 ].…”

Organic solvent nanofiltration (OSN) has been considered as one of the key technologies to improve the sustainability of separation processes. Recently, apart from enhancing the membrane performance, greener fabricate on of OSN membranes has been set as a strategic objective. Considerable efforts have been made aiming to improve the sustainability in membrane fabrication, such as replacing membrane materials with biodegradable alternatives, substituting toxic solvents with greener solvents, and minimizing waste generation with material recycling. In addition, new promising fabrication and post-modification methods of solvent-stable membranes have been developed exploiting the concept of interpenetrating polymer networks, spray coating, and facile interfacial polymerization. This review compiles the recent progress and advances for sustainable fabrication in the field of polymeric OSN membranes.
