Summary: This study resolves the problem of ArPD dissolution by using the DMF/H2O system and elucidates the behavioral differences of ArPD for different generations in film-forming. The separation performance of ArPD-based membranes is significantly improved by employing a patching strategy. The repaired membranes show excellent performance in the removal of small organics in an organic solvent system.

Summary: The successful synthesis of poly(aryl cyanurate) nanofiltration membranes via interfacial polymerization has been demonstrated. The membranes exhibit typical nanofiltration behavior with good molecular weight cutoff and permeance values. The membranes show negative surface charge and pH stability issues under extreme acidic and alkaline conditions due to hydrolysis of the aryl cyanurate bond.

Summary: This review paper focuses on the investigation of recently reported OSN thin-film composite (TFC) membranes, especially on the selective layer materials for non-polar solvents. Proper selection of monomers and additives for the selective layer can enhance microporosity, reduce transport resistance, and improve membrane performance. This paper could serve as a bridge to advance the development of next-generation OSN TFC membranes for non-polar solvents.

Summary: Thin film composite (TFC) membranes are widely used in reverse osmosis (RO)-based desalination processes due to their ideal separation performance. In this study, porous polyketone membranes prepared via non-solvent induced phase separation (NIPS) were explored as substrates for fabricating high-performance TFC membranes. Investigations on structure control and chemistry regulation showed that different polyketone substrates led to significant differences in thin layer formation during interfacial polymerization (IP), resulting in TFC membranes with varied permeance and performance.

Summary: The study successfully developed a thin-film composite membrane with excellent performance and stability for pharmaceutical concentration and solvent recovery. The membrane, after cross-linking treatment and synthesis of thin-film composite through interfacial polymerization, was solvent-activated to enhance permeability. In experiments, the membrane showed good permeability and rejection rates for acetone and methyl red.

Summary: This study presents a double-skin-layer nanofiltration membrane with porous organic polymer nanointerlayers prepared via a two-step interfacial polymerization technique, and investigates the significant influence of nanointerlayers with different pore sizes on membrane performance. It is found that an interlayer with a pore size of 4.22 nm can promote pure water permeance, compared to membranes without an interlayer.

Summary: The study demonstrates that incorporating fluorinated monomers into polyamide membranes can significantly enhance their permeability and selectivity for nonpolar solvents, improving their hydrophobicity and permeance. By preparing thin-film composite membranes through reactions in organic and aqueous phases, high-performance membranes suitable for use in petroleum refining and pharmaceutical purification can be obtained.

Summary: This study evaluates the influence of interfacial polymerization on the morphology and performance of polyamide thin film composite (TFC) membranes, considering varying monomer concentrations and organic phases with different physico-chemical characteristics. Two new descriptors, 'MPD supply' and 'TMC supply', are introduced to describe the synthesis-structure-performance relationship of polyamide TFC membranes. The study finds that well-performing membranes can be prepared until one of the monomers is added in excess, which depends on the interplay of MPD and TMC supply. The insights provided in this study can contribute to reducing the carbon footprint of reverse osmosis membrane synthesis and operation.

Summary: High performance TFC hollow fiber membranes were developed for ethanol dehydration by SIP modification with different amine-functionalized beta-cyclodextrin. Among all membranes, the one modified with 2wt% CD-EDA aqueous solution (SIP, pH=2) exhibited the best separation performance and permeation flux.

Summary: This study investigated the effect of interfacial polymerization temperature on the properties of thin film nanocomposite (TFN) nanofiltration membrane containing surface-functionalized graphene oxide (GO). The membrane developed at 55 degrees C exhibited a more cross-linked and rougher polyamide layer, resulting in excellent Na2SO4 rejection. However, it also had higher protein adhesion due to the rougher surface. On the other hand, the TFN membrane developed at 0 degrees C had a thin and smooth polyamide layer, resulting in higher water flux and improved antifouling performance.

Summary: This study investigates the feasibility of non-thermal sequential ultrafiltration-nanofiltration for concentrating mangosteen rind extract. The results show that both ultrafiltration and nanofiltration have high rejection towards total monomeric anthocyanin (TMA) and total phenolic content (TPC), with rates above 75% and 86%, respectively. Acidified solvents enhance the release of anthocyanin and phenolic contents but also result in membrane fouling and lower permeability.

Summary: Membrane modification with polydopamine can enhance membrane selectivity and compatibility. This study investigated the polymerization mechanism of dopamine on porous membranes and its impact on membrane performance. The results showed that polydopamine coating slightly reduced the membrane's pore size and formed aggregates on both the membrane surface and inner pores. The membrane's pore size significantly influenced the penetration and polymerization of dopamine.
