Novel mixed matrix membranes based on polyethersulfone and MIL-96 (Al) for CO2 gas separation

Recent Improvement Strategies on Metal-Organic Frameworks as Adsorbent, Catalyst, and Membrane for Wastewater Treatment

“…Generally, MOFs as single building materials of membrane are not applicable since MOFs are expensive and their high crystallinity can produce brittleness which limits their application in membrane technology [13]. Thus, MOF membranes were commonly growth on the support materials i.e., polymers or inorganic materials to reduce cost production and improves mechanical properties [117][118][119]. The other strategy that massively explored by researchers is mixing polymeric membranes with MOFs as filler to produce a hybrid membrane or mixed matrix membrane (MMM).…”

Progress of polyethersulfone composites and their applications in biomedical engineering

“…132 Likewise, Lestari et al reported that an addition of 10% MIL-100 (Al) can promote the selectivity of CO 2 /N 2 gas selectivity from 1.01 to 2.12 while the CO 2 /O 2 gas selectivity can be enhanced from 2.67 to 4.49 at 20 MIL-100 (Al) loading. 133 To enhance both the gas permselectivities and hemocompatibility, hydrophilic PAA hydrogel was introduced into the PVP/PES system by Zhi et al Beside improving CO 2 /O 2 permeabilities by 36.57% and 30.86% simultaneously, the composite membranes also displayed better hemocompatibility with prolonged activated partial thromboplastin time (APTT) (>10 s). 131 Similarly, Feng et al designed a CGEN network on a PES membrane as referred to in Section 2.1.2.…”

Metal–Organic Frameworks (MOFs)‐Based Mixed Matrix Membranes (MMMs) for Gas Separation: A Review on Advanced Materials in Harsh Environmental Applications

“…MILs derivatives, namely MIL-53(Al), MIL-68(Al), MIL-100(Al), MIL-100(Fe), MIL-101(Cr), and MIL-125(Ti) based MMMs will be comprehensively discussed in this section. [1,[38][39][40]67,68,[70][71][72][73][74][75] MIL-53(Al) consists of aluminium clusters and a terephthalate-based linker. It has diamond shape pore apertures that contribute to large pore volume and high surface area.…”

“…Lestari et al prepared MMMs with MIL-96(Al) in polyethersulfone (PES) polymer matrix for CO 2 separation. [1] The incorporation of filler improved the permeability and selectivity due to the filler-CO 2 affinity, attributed to the unsaturated metal sites with a partial positive charge in the filler that created dipole-quadrupole interaction between the filler and CO 2 . Besides, the free aromatic rings of the MIL-96(Al) ligand provided electron clouds which contributed to the interaction between CO 2 and filler.…”

“…These environmental issues are caused by the elevated emissions of greenhouse gases such as CO 2 , ozone (O 3 ), chlorofluorocarbons (CFCs), nitrous oxide (N 2 O), and hydrofluorocarbons (HFCs) in the atmosphere. [ 1 ] The greenhouse gases act as a “glass roof” that trap heat in the atmosphere and prevent them from releasing back to the Earth, leading to an increment in the global annual temperature. Their detrimental effect on environmental sustainability has urged searching the advancement in gas capture and utilization technology to eradicate this issue.…”
