“…Currently, printing methods are not limited to utilising inks comprised of plastics for art exhibitions and may also employ inks comprised of ceramics, metals, graphene additives, and even stimuli-responsive hydrogel composites [129] for prototyping and industrial applications [130][131][132]. Recently scaffolds [133], membranes [134][135][136], carbons [137], zeolites [138][139][140], aminosilicate adsorbents [141], and heterogeneous catalytic systems [142] by taking advantage of this technique.…”

HIGHLIGHTS• The advantages of macroporous metal-organic frameworks (MOFs) in comparison with micro-and mesoporous MOFs are discussed.• A range of synthetic methods for the fabrication and characterisation of hierarchical MOFs with macroporosity are reviewed.• The applications, advancements, and challenges of each method are compared and assessed in detail.ABSTRACT Introduction of multiple pore size regimes into metalorganic frameworks (MOFs) to form hierarchical porous structures can lead to improved performance of the material in various applications.In many cases, where interactions with bulky molecules are involved, enlarging the pore size of typically microporous MOF adsorbents or MOF catalysts is crucial for enhancing both mass transfer and molecular accessibility. In this review, we examine the range of synthetic strategies which have been reported thus far to prepare hierarchical MOFs or MOF composites with added macroporosity. These fabrication techniques can be either pre-or post-synthetic and include using hard or soft structural template agents, defect formation, routes involving supercritical CO 2 , and 3D printing. We also discuss potential applications and some of the challenges involved with current techniques, which must be addressed if any of these approaches are to be taken forward for industrial applications.

“…Bandalov et al incorporated inkjet printing with interfacial polymerization for the fabrication of thin film composite membrane for water desalination process. The membrane showed ~97.2% salt rejection and a ~26.4% increase in permeance [68]. Gao et al generated a patterned structure layer-by-layer on a microfiltration membrane with 0.2 µm pore diameter by incorporating inkjet printing with template synthesis [69].…”

Membrane Surface Patterning as a Fouling Mitigation Strategy in Liquid Filtration: A Review

et al. 2019

View full text Add to dashboard Cite

Membrane fouling is seen as the main culprit that hinders the widespread of membrane application in liquid-based filtration. Therefore, fouling management is key for the successful implementation of membrane processes, and it is done across all magnitudes. For optimum operation, membrane developments and surface modifications have largely been reported, including membrane surface patterning. Membrane surface patterning involves structural modification of the membrane surface to induce secondary flow due to eddies, which mitigate foulant agglomeration and increase the effective surface area for improved permeance and antifouling properties. This paper reviews surface patterning approaches used for fouling mitigation in water and wastewater treatments. The focus is given on the pattern formation methods and their effect on overall process performances.

“…However, these membranes are relatively thick and range from 300 to 800 nm. Yet, higher membrane thickness would generally lead to higher resistance, and, consequently, lower flux [95]. Livingston [96] postulated that ultrafast solvent permeance would be achieved when membrane thickness was reduced to 100 nm.…”

Microporous polymer membranes have been widely studied because of their excellent separation performance. Among them, polymers of intrinsic micro-porosity (PIMs) have been regarded as a potential next-generation membrane material for their ultra-permeable characteristics and their solution-processing ability. Therefore, many reviews have been reported on gas separation and monomers for the preparation of PIMs. This review aims to provide an overview of the structure-solubility property. Different structures such as non-network and network macromolecular structure made of different monomers have been reviewed. Then their solubility with different structures and different separation applications such as nanofiltration, pervaporation, and gas/vapor separation are summarized. Lastly, we also provide our perspectives on the challenges and future directions of the microporous polymer membrane for the structure-property relationship, anti-physical aging, and more.
