Abstract

PURPOSE: To prepare a gas separating member having excellent separation coefficient, a gas permeation amount as well as high mechanical strength compared with that of a conventional gas separating member, by forming a high-molecular thin membrane on a surface of a membranelike or a walllike porous substrate by plasma polymerization.
CONSTITUTION: An org. monomer is introduced into a space of a plasma state under vacuum in which a porous substrate comprising a porous film or a porous wall having pores with a diameter of several ten μ W several μm. Then, this org. monomer is converted to radiacal or ion by activation and polymerized to form a high-molecular membrane on the substrate. The thickness of this membrane is considered several ten Å or less. Moremover, as an org. monomer, for example, hexamethyldisiloxane is used. The gas separation ratio (O2/N2) of this gas separating member is 2, 3 or more and larger than that of a silicone membrane which is about 2.0.
