Hierarchically porous MOF/polymer composites via interfacial nanoassembly and emulsion polymerization

Abstract

In this work, we develop a general strategy for the preparation of robust hierarchically porous and readily processable MOF composites through an interfacial nanoassembly/emulsion polymerization method.

Controllable Synthesis of Metal-Organic Framework/Polyethersulfone Composites

“…One exception is HKUST-1/PES, which shows a degradation of one peak that is around 5.8 • (Figure 2b). The small peak corresponds to the (111) reflection and its degradation has been also observed in HKUST-1/acrylamide composites [12] and HKUST-1/cellulose acetate mixed matrix membranes [6]. The presence of solvent molecules in the pores of the synthesized pure HKUST-1 could associate with the small diffraction reflection at 5.8 • in Figure 2b.…”

“…The main preparation methods include phase inversion, casting and solvent evaporation, interface polymerization, in situ growth, and layer-by-layer self-assembly [3][4][5][6][7][8][9]. ZIF-8, UiO-66, Cr-MIL-101, and other MOFs have been successfully combined with polyvinylidene fluoride (PVDF), polyethylenimine (PEI), polystyrene (PS), and polymers of intrinsic microporosity (PIMs) [10][11][12][13]. Among them, polyethersulfone (PES), is broadly used in the field of filtration because of its outstanding properties such as oxidative, thermal, and hydrolytic stability, mechanical strength, and chemical inertness across the entire PH range [14,15].…”

Highly swelling pH-responsive microgels for dual mode near infra-red fluorescence reporting and imaging

“…[1][2][3][4][5][6][7] Fluorescence-based technologies provide relatively simple and inexpensive operating procedures whilst delivering real-time imaging and diagnostic data 8,9 with high sensitivity, 10,11 low background noise 12 and potentially low-cost imaging reagents. 13,14 The reporter probes studied to date include organic dyes, 15 uorescent dots, 16 plasmonic nanomaterials, 17 uorescent proteins 18 and upconverting nanoparticles. 16 However, uorescent probes can have limited…”

Self‐Templated Assembly of AuI/AgI‐Thiolate Sheets with Central Holes

“…Self-assembly has been avery important technique to fabricate nanostructures nowadays, [1] and multi-componentc o-assembly has merits in building up complex structures, [2][3][4][5] integration of diversified functions, [2,6] andr ealization of enhanced or new properties that single components are not capable of. [3,4,[7][8][9][10][11][12][13] Amongt he various phase structures of the co-assemblies, such as amorphous phase, [14] liquid crystal, [7] crystal [8] and other complicated phase structures [3][4][5] that lie between the above simple ones, crystalline ones are outstanding in precisely modulating the properties of materials owing to the high structural order, [9,10] but especially hard to achieveb ecause it requires the good match in the crystal latticeso ft he constituents, otherwise, phase separation will happen.…”
