The prospect of synthesis of PES/PEG blend membranes using blend NMP/DMF for CO2/N2 separation

Abstract Carbon dioxide (CO 2 ) emissions have been the root cause for anthropogenic climate change. Decarbonisation strategies, particularly carbon capture and storage (CCS) are crucial mitigating risk of global warming. Among all current CO separation technologies, membrane has biggest potential CCS as it is inexpensive, highly efficient, simple to operate. Polymeric membranes preferred choice gas industry due simpler methods fabrication lower costs compared inorganic or mixed matrix (MMMs). However, plasticisation upper-bound trade-off between selectivity permeability limited performance polymeric membranes. Recently, researchers found that blending glassy rubbery polymers can effectively minimise permeability. Glassy poly(ethersulfone) (PES) poly(ethylene) glycol (PEG) known a high affinity towards . In this paper, PEG PES reviewed polymer blend yield final with permeance /nitrogen (N selectivity. Gas properties be enhanced by using different solvents in phase-inversion process. N-Methyl-2-Pyrrolidone (NMP) Dimethylformamide (DMF) common industrial used fabrication. Both NMP DMF prospective solvent improve morphology PES/PEG their effects on structure which increases permeation well Thus, fabricated believed major prospect /N separation.
