Preparation methods are presented of thin dual layer membranes (DLM's) and mixed matrix membranes (MMM's) based on nanosheets of the Cu-BDC metal-organic framework (MOF, lateral size range 1–5 µm, thickness 15 nm) and commercially available poly(ethylene oxide)–poly(butylene t ...
Towards High Performance Metal–Organic Framework–Microporous Polymer Mixed Matrix Membranes
Addressing Compatibility and Limiting Aging by Polymer Doping
Membrane separation for gas purification is an energy-efficient and environment-friendly technology. However, the development of high performance membranes is still a great challenge. In principle, mixed matrix membranes (MMMs) have the potential to overcome current materials ...
Revisiting the Aluminum Trimesate-Based MOF (MIL-96)
From Structure Determination to the Processing of Mixed Matrix Membranes for CO2 Capture
A microporous Al trimesate-based metal-organic framework (MOF), denoted MIL-96-(Al), was selected as a porous hybrid filler for the processing of mixed matrix membranes (MMMs) for CO2/N2 postcombustion separation. First, the structural model of MIL-96-(Al ...
Affinity layers play a crucial role in chemical sensors for the selective and sensitive detection of analytes. Here, we report the use of composite affinity layers containing Metal Organic Frameworks (MOFs) in a polymeric matrix for sensing purposes. Nanoparticles of NH2< ...
The preparation and performance of mixed matrix membranes (MMMs) based on polybenzimidazole (PBI) and ZIF-8 nanoparticles of different average sizes (50, 70 and 150 nm) as filler are reported. MMMs containing 10 and 20 wt% of ZIF-8 were tested for H2/CO2 ...
Adsorption of CO2 on MIL-53(Al) and NH2-MIL-53(Al) has been studied by Fourier transform infrared (FTIR) spectroscopy at different temperatures and equilibrium pressures. For better interpretation of the spectra 13CO2 was also utiliz ...
Metal Organic Framework Crystals in Mixed-Matrix Membranes
Impact of the Filler Morphology on the Gas Separation Performance
Mixed-matrix membranes comprising NH2-MIL-53(Al) and Matrimid or 6FDA-DAM have been investigated. The metal organic framework (MOF) loading has been varied between 5 and 20 wt%, while NH2-MIL-53(Al) with three different morphologies, nanoparticles, nanoro ...
