Claim:
1. A composite permeable membrane for separation of a first gas from a second gas; said composite permeable membrane comprising: at least one layer of a perforated permeable two-dimensional material; and at least one membrane of a material other than a two-dimensional material, said membrane being characterized by a permeability for said first gas greater than or equal to 1 Barrer, wherein said composite permeable membrane is constructed of said at least one layer of the perforated permeable two-dimensional material and said at least one membrane and arranged to provide preferential transport of said first gas relative to said second gas through said at least one membrane and said at least one layer of said perforated permeable two-dimensional material, wherein said at least one membrane and said at least one layer of said perforated permeable two-dimensional material are provided in a stacked multilayer geometry, and wherein said each of said at least one layer of said perforated permeable two-dimensional material provided in said stacked multilayer geometry is independently positioned between first and second adjacent membranes.
