ABSTRACT:
A gas separating member of the present invention comprises a porous substrate in the form of a film, wall or hollow fiber and a polymer film formed on a surface of the substrate by plasma polymerization. The gas separation factor (O.sub.2 /N.sub.2) ranges from 2.3 to 3.9 with the corresponding gas permeability ranging from 12 to 0.16 liter/min. m.sup.2 atm. pres.-air.
A modified gas separating member of the present invention, which comprises a porous substrate in the aforementioned form and two polymer films formed on a surface of the substrate by plasma polymerization, has the gas separation factor (He/H.sub.2) ranging from 14 to 45.
