“…Another option for controlling the membrane formation process is introducing the surfactants additive in the casting solution, which has a significant impact on the structure of membranes by affecting the interfacial properties between the coagulant and the polymer solution 8,21 . When a hydrophilic coagulant, typically water, is used, hydrophilic surfactants can enhance the formation of macrovoids, whereas hydrophobic surfactants cannot.…”

The incorporation of non-solvent organic additives in the casting solution has emerged as a significant technique in membrane fabrication. This approach enables the manipulation of membrane morphology and facilitates the preparation of high-performance membranes. Our work focusing on investigating the impact of various organic additives on the development of integrally skinned polyetherimide asymmetric nanofiltration membranes, which has not been explored in solvent resistant nanofiltration (SRNF). The additives investigated in this study can be classified into three categories: hydrophilic monomers, hydrophilic polymer and surfactant additives. The effect of these organic additives on PEI membrane performance was evaluated by separating methylene blue (MB, molecular weight 374 Da) from ethanol solution, and membrane morphology was characterized by scanning electron microscope (SEM).

“…This allows for the production of versatile membranes. Conventional additives consisting of polymers [3][4][5] , inorganic salts 6 and surfactants 7,8,9 , are frequently used for this purpose. Consequently, the incorporated additives in casting solution can affect membrane morphology and performance.…”

“…Nowadays, there is an emerging demand to design and plan for sustainable water treatment processes that are environmentally kind as well as energy efficient. In this context, the use of forward osmosis (FO) membranes for water purification has shown great potential as they provide the advantage of operating at lower energy requirements, while providing smaller fouling tendencies, − when compared to their counterpart [i.e., reverse osmosis (RO)] . Furthermore, FO systems can work in combination with additional treatment systems for water desalination, reclamation, and wastewater handling. , …”

The design of functionalized selective layers to develop novel membranes is essential to provide potential solutions that meet the continuously growing demand of providing safe water. Herein, we present the interfacial response of an enzymatic thin-film composite (E-TFC) membrane displaying dual functionality and fabricated as a proof-of-concept for both efficient lipopolysaccharide (LPS) separation and ester bond hydrolysis. The enzymatic membrane model was constructed by employing lipase b from Candida antarctica (CALB) covalently coupled via chemically activated bisepoxide groups onto the surface of the di-block copolymer polystyrene-b-poly(4-vinyl pyridine) (PS-b-P4VP) layer. Our results show a complete rejection of size-excluded LPS molecules when using the fabricated E-TFC membrane in a forward osmosis (FO) application. Moreover, the immobilized enzyme was able to retain 97% of its enzymatic activity when using 4-nitrophenyl acetate (pNPA) and up to 74% to liberate free fatty acids from LPS molecules within the feed side of the FO system. This work provides fundamental insights into new emerging functional biomaterials that find applications in hybrid catalytic filtration processes that also selectively remove LPS molecules from water sources.
