“…The hydroxyl group can raise membrane resistance to BSA molecules and limit foulant from building up on the membrane. A similar finding was also reported on the enhanced membrane antifouling properties from incorporated nanomaterial (Balcik et al., 2022). The creation of the hydration layer increases membrane surface resistance due to the availability of Cys and CuO NPs, which attract more water molecules.…”

Membrane technology has been extensively applied for protein separation. A membrane with reliable filtration performance and high removal efficiency is required. In this study, an ultrafiltration (UF) membrane was fabricated by dry‐wet phase inversion to incorporate copper oxide nanoparticles (CuO NPs) with a different ratio of L‐cysteine (Cys) in polysulfone (PSf). The characterization of the membrane involves using scanning electron microscopy (SEM), water contact angle, water content, pore size, and porosity analysis. The membrane performance evaluation includes flux permeation and bovine serum albumin (BSA) removal as a protein foulant. The membrane antifouling feature was examined by dynamic filtration of BSA. It was found that the Cys to CuO NPs ratio of 1.7:1 gives an optimal value on flux permeation and protein removal. The membrane exhibited high removal of BSA with 96.3%, and optimum water flux was achieved at 173.3 L/m2h, respectively. The highest permeability of aqueous BSA permeate at 500 ppm was about 111 L/m2h and 82.5 L/m2h for 1000 ppm. The enhancement of PSf‐Cys‐CuO membrane performance could be due to its lower contact angle (68.7°), high porosity (68%), and ideal pore size (46 nm) as well as showing good morphological structure. Most significantly, the inclusion of Cys improves antifouling capabilities. The membrane showed a lower chance of fouling based on the evaluation of the relative flux reduction and flux recovery ratio. Hence, the availability of Cys has a better impact on the polymer‐based membrane and seems promising for protein separation applications.

“…In addition to the pure LDHs membranes, composite membranes blending with LDHs nanoparticles are proposed in recent years. [ 67,76 ] The various methods of the preparation of LDHs membranes are summarized in Table 2 . In contrast to conventional porous membranes with wide pore size distribution, substantial average pore size, and intricate pore structures, LDH nanomaterials offer a distinct advantage in providing well‐structured and uniform pores, thereby enabling high‐performance separation.…”

Layered double hydroxides (LDHs) consist of metal cations with positive charges and anions located between their layers, resulting in a structured gallery height and a wide array of surface functionalities. In recent years, LDHs have garnered substantial attention due to their expanded application range through the development of LDHs membranes, bringing exciting possibilities across various fields. A deep understanding of mass transport mechanisms is essential for designing membrane materials effectively and enhancing separation processes. In this review, In this review, the strategies employed for creating continuous and well‐intergrown LDHs membranes are first elaborated. Subsequently, the study delves into a detailed discussion of the selective transport processes involving gas molecules, liquid molecules, and ions through LDHs membranes. Based on the interactions between permeated molecules and LDHs membranes, the mass transport mechanisms can be concluded in molecular sieving mechanism, solution‐diffusion mechanism and facilitated transport mechanism. Finally, the current challenges and future perspectives are outlined.

Functionalization of polyvinylidene fluoride (PVDF) was carried out by two different methodology namely, aza-Michael addition and free radical reaction from the dehydrofluorinated PVDF. Functionalization agents like 2MI, CR, and indole were grafted onto KOH treated PVDF via aza-Michael addition reaction whereas MAH and MI were grafted onto the same via free radical reaction. The functionalized PVDF was characterized by FTIR, DSC, TGA, WCA measurement, SEM, and EDX. Further, the MAH grafted PVDF was doped with V 2 O 5 nanoparticles to form a catalytic membrane. Transesterification reaction (TER) was done using the PVDF-g-MAH/V 2 O 5 membrane but ended with negative results due to the low residential time. Hence, it was done in a conventional technique in the presence of pieces of membrane material as a template. The product with the red shift in the absorbance spectrum confirmed the TER.
