tThe organic–inorganic hybrids of poly(amide-6-b-ethylene oxide) (PEBA) and silica utilizing aminopropy-ltriethoxysilane (APTES) as precursor was prepared via sol–gel process and was compared with neatPEBA. The nanodispersed inorganic network produced in the organic matrix was structurally character-ized using Fourier transform infrared (FT-IR) that revealed the existence of different chemical groupscorresponding to the silica precursors. The single gas permeability was carried out for neat PEBA andPEBA-nano silica (10 wt.% precursor) membranes. CO2permeability for the neat polymer membrane washigher than the nano-composite membrane and increased with pressure. Adding 10 wt.% of nanosilicafiller into the polymeric matrix caused CO2permeability to decrease.
