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.
