Progress in Multifunctional Metal–Organic Frameworks/Polymer Hybrid Membranes

Abstract

The fabrication of state-of-the-art membranes with customized functions and high efficiency is of great significance, but presents challenges. Emerging metal-organic frameworks (MOFs)/polymer hybrid membranes have provided bright promise as an innovative platform to target multifunctional hybrid materials and devices; this is thanks to their unique properties, which come from three components that are collaboratively enforced. This minireview provides a brief overview of recent progress in the construction of such hybrid membranes, and highlights some of their very important applications in separation, conduction, and sensing.

Application of Nanozymes in Environmental Monitoring, Management, and Protection

“…It is worth noting that most metal oxide nanomaterials exhibit lower Km than HRP, which provides the possibility for a wide range of applications. Metal-organic frameworks (MOFs) are porous coordination crystalline materials formed by the self-assembly of metal ions (or metal clusters) and organic ligands through the principles of coordination chemistry [ 28 ]. In recent years, some MOFs exhibit their own good enzyme mimicking properties, mimicking the functions of a variety of enzymes, including oxidases, peroxidases, catalases, superoxide dismutases, and hydrolases.…”

A rapid self-healing glassy polymer/metal–organic-framework hybrid membrane at room temperature

“…[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] To transform laboratory-synthesized MOF powders into industrially viable products, much effort has been devoted to constructing MOF-polymer hybrid materials that not only retain the inherent properties of their individual components, but also possess some collaboratively enforced functions beyond these discrete composites. [27][28][29][30][31][32][33] For example, polymers endow MOFs powders with desired processability and flexibility; on the other hand, in addition to display functions, MOFs may also act as multiconnected cross-linking agents to further enhance the mechanical strength of the polymer. 34,35 In some cases, polymers rich in hydrogen bonds or dynamic covalent bonds also bring self-healing abilities to the hybrid materials; 36 however, an external energy input, such as heating, is required.…”
