“…The well-dispersed ZIF-67 nanoparticles exhibited excellent catalytic activity and improved the membrane porosity. To date, numerous studies have reported the application of MOF materials, including UiO-66 (Wan et al, 2020;Wang et al, 2021), ZIF-8 (Karimi et al, 2019), HKUST-1 (Yang et al, 2021), and MIL-101 (Ni et al, 2021). Among these materials, MIL-53(M) series have attracted much attention due to its chemical versatility, flexible structure, breathing feature and stability (Naeimi and Faghihian, 2017).…”

Polyvinylidene fluoride (PVDF), with excellent mechanical strength, thermal stability and chemical corrosion resistance, has become an excellent material for separation membranes fabrication. However, the high hydrophobicity of PVDF membrane surface normally leads a decreased water permeability and serious membrane pollution, which ultimately result in low operational efficiency, short lifespan of membrane, high operation cost and other problems. Metal-organic frameworks (MOFs), have been widely applied for membrane modification due to its large specific surface area, large porosity and adjustable pore size. Currently, numerous MOFs have been synthesized and used to adjust the membrane separation properties. In this study, MIL-53(Al) were blended with PVDF casting solution to prepare ultrafiltration (UF) membrane through a phase separation technique. The optimal separation performance was achieved by varying the concentration of MIL-53(Al). The surface properties and microstructures of the as-prepared membranes with different MIL-53(Al) loading revealed that the incorporation of MIL-53(Al) enhanced the membrane hydrophilicity and increased the porosity and average pore size of the membrane. The optimal membrane decorated with 5 wt% MIL-53(Al) possessed a pure water permeability up to 43.60 L m−2 h−1 bar−1, while maintaining higher rejections towards BSA (82.09%). Meanwhile, the prepared MIL-53(Al)/LiCl@PVDF membranes exhibited an excellent antifouling performance.

“…Nanocellulose produced via a TEMPO-mediated method had better anti-fouling properties. Yang et al (2021) [49] reported that the TEMPO-CNF-coated PAN membrane exhibited a high permeation flux (15-61 L m −2 h −1 at 0.5 psi) and rejection ratio (>98%), as well as good antifouling against the model pollutant (BSA) using simple hydraulic flushing. Good filtration performance of the TEMPO-CNF can be explained by the strong electrostatic repulsion between the negatively charged TEMPO-CNF.…”

Extensive research and development in the production of nanocellulose production, a green, bio-based, and renewable biomaterial has paved the way for the development of advanced functional materials for a multitude of applications. From a membrane technology perspective, the exceptional mechanical strength, high crystallinity, tunable surface chemistry, and anti-fouling behavior of nanocellulose, manifested from its structural and nanodimensional properties are particularly attractive. Thus, an opportunity has emerged to exploit these features to develop nanocellulose-based membranes for environmental applications. This review provides insights into the prospect of nanocellulose as a matrix or as an additive to enhance membrane performance in water filtration, environmental remediation, and the development of pollutant sensors and energy devices, focusing on the most recent progress from 2017 to 2022. A brief overview of the strategies to tailor the nanocellulose surface chemistry for the effective removal of specific pollutants and nanocellulose-based membrane fabrication approaches are also presented. The major challenges and future directions associated with the environmental applications of nanocellulose-based membranes are put into perspective, with primary emphasis on advanced multifunctional membranes.

“…Cellulose acetate (CA) is a semisynthetic, biocompatible derivative of cellulose produced through acetylation of the hydroxyl groups, which is one of the most important esters of cellulose. − The synthesis process of CA gives a desirable degree of substitution, and thus, CA can be subdivided into cellulose monoacetate, cellulose diacetate, and cellulose triacetate. , The applications of CA vary from the textile industry to plastic devices, membranes, filters, and packaging. − However, CA often suffers from poor tensile and ductile properties, which restrict its extensive use. ,, As a result, it is necessary to improve the performance of CA to produce stronger and more ductile materials.…”

It is significant to understand the interfacial interactions involved between the cellulose acetate (CA) and dispersed nanomaterials, in which the enhanced interaction improves the mechanical behavior of CA. In this work, the amendments of CA with SiO 2 nanoparticles have been found to be endowed by grafting varying concentrations (0, 3, 5, and 6%) of octadecyltrichlorosilane (OTS). Aided by SiO 2 colloid probe atomic force microscopy (AFM with a probe diameter of 20 μm), the adhesion force between CA and SiO 2 is found to be programmable by tuning OTS concentrations functionalized onto SiO 2 surfaces. The adhesion forces of 5% OTSfunctionalized SiO 2 with CA are the strongest, followed by the ones of 0, 3, and 6% OTS, resulting in a smoother and denser morphology on the film with 5% OTS. The AFM-measured approaching force−distance curves have been further compared to predictions by the extended Derjaguin−Landau−Verwey−Overbeek (XDLVO) theory, in which the XDLVO force is summed as the Liftshitz−van der Waals force (F LW ), the electrostatic double-layer force (F EL ), and the acid−base interaction force (F AB ). F LW and F EL do not change significantly with OTS concentrations functionalized onto SiO 2 . However, F AB is sensitive to the functionalized OTS concentration onto SiO 2 and significantly contributes to the interaction force of the composite films with 5% OTS, promoting the formation of a smooth and dense surface feature with a considerable mechanical performance demonstrated by load−displacement curves from a nanoindenter. This is highly encouraging and suggests that nanomaterials can be incorporated into CA to effectively improve their mechanical compatibility by programming the interaction between the CA matrix and nanomaterials.
