In this research, functionalized graphite nanoplatelets (F-GNP) were synthesized and then hybridized by Fe3O4 to prepare Fe3O4-F-GNP nanoparticles. The synthesized nanoparticles were analysed by FTIR and FESEM experiments and were used as dispersed phase in mixed matrix gas separation membrane fabrication. Mixed matrix (polyether sulfone+ Fe3O4-F-GNP) and neat polymeric (polyether sulfone) membranes were fabricated by wet phase inversion method and characterized by FESEM and gas permeation tests using pure CO2 and CH4 as test gases. Gas permeation test results showed that addition of 1 wt. % Fe3O4-F-GNP to polymeric solution can increase both CO2 and CH4 permeances of result mixed matrix membranes several times. This phenomenon was attributed to Fe3O4-F-GNP structural properties which acts as layered sheets inside the polymer matrix.
