GAS SEPARATION MEMBRANE ON MICROPOROUS POLYOLEFIN SUPPORT |
摘要 |
<p>A gas separation membrane has: a polymeric microporous membrane which has a polyolefin as a main component, and which is manufactured by wet phase separation process, and has a porosity of 20 to 80%, an average pore diameter of 1 to 100 nm and a piercing strength at 100°C of 2 to 50 N; and a gas-separating thin film, which is provided on at least one surface, and/or the interior of the polymeric microporous membrane, and which comprises a fluorine-containing gas-separating resin as a main component, and has an average thickness of 0.01 µm to less than 0.4 µm. The gas separation membrane having an oxygen-nitrogen separation factor not smaller than 1.4.</p> |
