Roll‐to‐Roll Production of Metal‐Organic Framework Coatings for Particulate Matter Removal

Abstract

A powerful roll-to-roll hot-pressing strategy for mass production of metal-organic framework (MOF)-based filters (MOFilters) using various MOF systems with ranges of substrates is presented. Thus-obtained MOFilters show superior particulate matter removal efficiency under desired working temperatures. Such versatile MOFilters can be scaled up and purposely designed, which endows MOFilters with great potentials in both residential and industrial pollution control.

Ultrarobust Biochips with Metal–Organic Framework Coating for Point-of-Care Diagnosis

“…Metal-organic frameworks (MOFs), comprised of metal ions or clusters linked by organic ligands, 24–25 have shown promising applications in gas and energy storage, 26–27 drug delivery, 28 catalysis, 29–30 separation, 31–32 and chemical sensors. 33 Their attractive properties include large surface area, tunable porosity, organic functionality, stable shelf-life and excellent thermal stability.…”

Flexible and Hierarchical Metal–Organic Framework Composites for High‐Performance Catalysis

“…[1] MOFs are well-known for their extraordinarily high porosity and internal surface areas. [12] Eddaoudi group reported the MOF/silica composite by the stepwise layer-by-layer strategy. [8] However, most MOFs are rigid, brittle, and very easy to be crumbled.…”

“…[8] However, most MOFs are rigid, brittle, and very easy to be crumbled. [12] Eddaoudi group reported the MOF/silica composite by the stepwise layer-by-layer strategy. [10] All of these disadvantages have largely limited their practical applications in various domains.T ot ackle this problem, tremendous efforts have been made to hybridize MOFs with other materials,thus realizing the combination of their advantages and circumventing shortcomings.Avariety of MOF composites have been successfully developed, such as MOF/graphene, [11a] MOF/graphite, [11b] MOF/carbon nanotubes, [11c] MOF/polymers, [11d] MOF/enzymes, [11e] and MOF/metal nanoparticles, [11f] generating new properties unavailable from either component.…”

“…[9] Furthermore,M OFs are insoluble in any solvents and have no exact melting points, which means that they cannot be processed by traditional solvent or heat-based techniques. [12] Eddaoudi group reported the MOF/silica composite by the stepwise layer-by-layer strategy. Very recently,W ang and co-workers successfully developed the MOF/mesh, MOF/cloth, and MOF/sponge composites via the roll-to-roll mechanical production and utilized them for efficient particulate matter removal.…”

“…In contrast to other MOF composites,the morphology of PCN-224 was well-retained in PCN-224(Fe)/MF,without losing the inherent structural periodicity of crystalline materials.T hermogravimetric analysis (TGA) result revealed the PCN-224(Fe)/MF composite was thermally stable up to 300 8 8Ci n nitrogen (Supporting Information, Figure S1). [12][13][14] In contrast, the direct mixing of excessive PCN-224(Fe) and melamine foam lead to am aximum loading amount of 11 %.
