A series of dense membranes for gas separation based on poly[bis(phenoxy)phosphazene] (PPOP) were prepared in flat sheet configurations. They were characterized by viscosimetry, differential scanning calorimetry (DSC), thermogravimetry (TG), X-ray diffraction (XRD) and scanning electron microscopy (
The permeability of a composite membrane consisting of a homogeneous layer and a porous layer has been derived theoretically by assuming that the permeation through the homogeneous layer obeys Fick's law and that permeation through the porous layer is free molecular flow. The activation energy of th
