Preparation and characterization of small-size amorphous MOF mixed matrix membrane

Ultrasonically synthesized MOFs for modification of polymeric membranes: A critical review

“…High MOF loads may cause particle aggregation, leading to water flux reduction and membrane swelling. Besides, some recent research indicated that MOFs with smaller sizes are more compatible with the host polymers [60] . The incorporation of the ultrasmall MOFs particles into the polymer matrix effectively reduced the formation of non-selective microvoids around the particles and enhanced substantially the membrane selectivity [61] .…”

Construction of boric acid‐functionalized metal–organic frameworks for glycopeptide recognition in the serum of cervical cancer patients

“…Metal–organic frameworks (MOFs), porous materials composed of metal ions and organic ligands, have the characteristics of easy functionalization, high surface area and high porosity, and have been widely used in the fields of catalysis, gas adsorption and drug delivery 21–23 . In recent years, the application of MOFs in proteomics, particularly phosphopeptide enrichment, enzyme immobilization and glycopeptide enrichment, has emerged 24–26 .…”

“…Metal-organic frameworks (MOFs), porous materials composed of metal ions and organic ligands, have the characteristics of easy functionalization, high surface area and high porosity, and have been widely used in the fields of catalysis, gas adsorption and drug delivery. [21][22][23] In recent years, the application of MOFs in proteomics, particularly phosphopeptide enrichment, enzyme immobilization and glycopeptide enrichment, has emerged. [24][25][26] As is well known, the post-synthesis strategy for modification based on a prefabricated framework can not only maintain the chemical structure and properties, but also provide corresponding functions on demand in advance.…”

UiO‐66‐NH2 particle size effects on gas separation performance of cellulose acetate composite membranes

“…24,25 Crystal engineering such as building core-shell structure, modifying crystal surface, and adjusting particle size has been employed to minimize interfacial defects, in which the particle size of MOF has huge influence on the interfacial compatibility of MMMs. 26,27 Micrometer-sized MOF fillers can provide highly efficient gas transport channels, while the large filler/polymer interfacial gaps and the poor adhesion will deteriorate the membrane selectivity. By contrast, nanosized MOF fillers are preferred for MMMs as they can reduce the nonselective gaps.…”

“…To date, the construction of defect‐free MMMs is still challengeable due to the existence of nonselective voids and particle agglomeration during the incorporation of MOFs into polymer matrixes 24,25 . Crystal engineering such as building core‐shell structure, modifying crystal surface, and adjusting particle size has been employed to minimize interfacial defects, in which the particle size of MOF has huge influence on the interfacial compatibility of MMMs 26,27 .
