Gas-permeable laminate. |
摘要 |
<p>A gas-permeable laminate for separating a specific gas from a gaseous mixture comprising a gas-permeable membrane having excellent selectivity for the specified gas and a porous support supporting said membrane, said gas-permeable membrane being a multilayer laminated membrane comprising at least a first and a second ultrathin membrane having exceltent selectivity for the specified gas and a third ultrathin film of a different material from the materials of the first and second ultrathin membranes and located between the first and second ultrathin membranes, the material of the third ultrathin membrane having a higher permeation coefficient with respect to the specified gas than the materials of the first and second ultrathin membranes.</p> |
