Influence of Dialysis Membranes on Clinical Outcomes: From History to Innovation

open access: yesMembranes, 2022
Dialysis membranes were traditionally classified according to their material compositions (i.e., as cellulosic or synthetic) and on the basis of the new concept of the sieving coefficient (determined by the molecular weight retention onset and molecular ...

Long-Term Stable Metal Organic Framework (MOF) Based Mixed Matrix Membranes for Ultrafiltration

open access: yes, 2020
In this study, novel mixed matrix polyethersulfone (PES) membranes were synthesized by using two different kinds of metal organic frameworks (MOFs), namely UiO-66 and UiO-66-NH2.

Preparation and high CO2/CH4 selectivity of ZSM-5/Ethyl cellulose mixed matrix membranes

open access: yesMaterials Research Express, 2021
It is known that natural gas is extracted with a large amount of CO _2 , which reduces the amount of heat generated during the combustion of natural gas. How to remove some of the CO _2 from the natural gas is a problem that needs to be solved.

Mixed matrix membranes embedded with Janus mesoporous silica nanoparticles for highly efficient water treatment

open access: yeseXPRESS Polymer Letters, 2021
A periodic mesoporous organosilica (PMO) Janus nanoparticle (PMO-SO3H&SiO2-NR) was gently synthesized and mixed with polyethersulfone (PES) to fabricate a series of mixed matrix membranes via the phase inversion method.

Tortuous mixed matrix membranes: A subtle balance between microporosity and compatibility

open access: yesJournal of Membrane Science, 2021
In this work, the effectiveness of metal-organic frameworks (MOFs) with sheet-like morphologies was assessed as function of the MOF microporosity and MOF-matrix compatibility. Zeolitic imidazolate frameworks (ZIFs, a MOF subclass) with sheet-like/platelet morphologies were incorporated in Matrimid/PBI matrices resulting in mixed matrix membranes (MMMs).

High Selective Mixed Membranes Based on Mesoporous MCM-41 and MCM-41-NH2 Particles in a Polysulfone Matrix

open access: yesFrontiers in Chemistry, 2019
The development of membrane technology for gas separation processes evolved with the fabrication of so-called mixed matrix membranes (MMMs) as an alternative to neat polymers, in order to improve the overall membrane effectiveness.

Combination of MOFs and Zeolites for Mixed‐Matrix Membranes

open access: yesChemPhysChem, 2011
AbstractMixed‐matrix membranes (MMMs) were prepared by combinations of two different kinds of porous fillers [metal‐organic frameworks (MOFs) HKUST‐1 and ZIF‐8, and zeolite silicalite‐1] and polysulfone. In the search for filler synergy, the MMMs were applied to the separation of CO2/N2, CO2/CH4, O2/N2, and H2/CH4 mixtures and we found important ...

Nanocarbon-Based Mixed Matrix Pebax-1657 Flat Sheet Membranes for CO2/CH4 Separation

open access: yes, 2023
In the present work, Pebax-1657, a commercial multiblock copolymer (poly(ether-block-amide)), consisting of 40% rigid amide (PA6) groups and 60% flexible ether (PEO) linkages, was selected as the base polymer for preparing dense flat sheet mixed matrix ...

Membrane materials targeting carbon capture and utilization

open access: yesAdvanced Membranes, 2022
Over the past decades, fossil fuel combustion has emitted large quantities of CO2 into the atmosphere, resulting in global climate change. Nowadays, it's considered a feasible strategy to capture CO2 from some significant point sources.
