## Abstract A study was conducted to measure the permeability to oxygen (PmO~2~) of microporous membranes coated with ultraβlowβtemperature isotropic (ULTI) carbon. Carbonβsurfaced membranes were fabricated by application of a thin complete layer (0.7 to 1.7 microns thick) of ULTI carbon onto one s

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
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 (
