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
The permeability coefficients for a number of common gases passing through a F'TFE film used in an electrochemical sensor are reported. A comparison with published data, recalculated into similar units, shows a large spread of values found for the permeability of PTFE films, possibly due to the diff
