Polyethylene Glycol (PEG) Additive in Polymer Membranes for Carbon Dioxide Separation: A Critical Review on Performances and Correlation with Membrane Structure

Separations, Год журнала: 2025, Номер 12(3), С. 71 - 71

Опубликована: Март 16, 2025

The efficient separation and removal of carbon dioxide (CO2) from its mixtures is an important technological challenge to limit effects resulting the increase concentration in atmosphere. Membrane technology environmentally friendly approach, highly scalable less energy-consuming than conventional methods such as adsorption, absorption cryogenic separation. Hybrid membrane materials incorporating inorganic filler nanostructures polymer matrices having polyethylene glycol (PEG) a plasticized additive are promising given presence CO2-philic polar functional groups PEGs structural refinements on blend matrix consequent distribution. In this review, literature information hybrid polymer/PEG membranes critically reviewed discuss how dispersion gives rise enhanced CO2 performances with respect those obtained traditional mixed where dispersed neat polymer. discussion will be focused correlation between transport properties, properties defect polymer-filler incompatibility. It shown that simultaneously offer improved mechanical compared nanocomposite ones particles matrix. PEG addition enhances filler-matrix compatibility, delays aggregation limits formation interface defects.

Polymers of intrinsic microporosity with internal dihedral lock for efficient gas separation

Advanced Membranes, Год журнала: 2024, Номер 4, С. 100097 - 100097

Опубликована: Янв. 1, 2024

Polymers of intrinsic microporosity (PIMs) stand out as promising membrane materials with exceptional separation performance. In this study, we crafted a highly efficient gas using an emerging material, called cyclohexyl-fused spirobiindane-based PIM (CCS-PIM). The CCS-PIM features robust and rigid microporous structure high specific surface area (SBET=704.6 m2/g), exhibiting excellent CO2-selective adsorption capacity. CO2 uptake is 0.78 mmol/g at 273 K 0.15 bar, leading to IAST selectivity 25.2 for CO2/N2 (15/85 v/v) 16.7 CO2/CH4 (50/50 298 K. precisely tuned pore size the leads enhanced molecular sieving effect, showcasing superior across various pair separations. It demonstrates O2/N2 6.03 26.1, surpassing 2008 Robeson upper bounds. This study suggests strategic method improve efficiency by customizing locked precise through insertion variously sized rings.
