Ionomer-Clay hybrid membranes were prepared by melt intercalation method with twin extruder. MMT was intercalated or exfoliated by the ionomer and it was confirmed by X-ray diffraction method. D-spacing of the characteristic peak from MMT plate in WAXD was moved and diminished. Gas permeability, mechanical properties and thermal properties of the ionomer-clay hybrid membranes were investigated. Gas permeability through the ionomer-clay hybrid membranes decreased due to increased tortuosity made by intercalation of clay in Ionomer.

SEBS-clay hybrid membranes were prepared by melt intercalation method with internal mixer. In the hybrid, the amount of clay content was fixed to 5 phr. MMT was intercalated or exfoliated by the ionomer and it was confirmed by X-ray diffraction method. D-spacing of the characteristic peak from MMT plate in SAXD was moved and diminished. Gas permeability, mechanical properties and thermal properties of the SEBS-clay hybrid membranes were investigated. Gas permeability through the SEBS-clay hybrid membranes decreased due to increased tortuosity made by intercalation of clay in SEBS.
