Development of PVDF/PEG Thin Film Composite Membrane For CO2/N2 Gas Separation

PVDF/PEG) thin film composite (TFC) membrane for CO2/N2 gas separation. Asymmetric thin flat sheet membrane was prepared by dry wet phase inversion process consisting 15 %w/v of (PVDF) as the support layer polymer, 82 %w/v of N-methyl-2- pyrrolidone (NMP) as the solvent and 3 %w/v of distilled water...
