Enzymatically active high-flux selectively gas-permeable membranes
| DWPI Title: Membrane structure for moving object species from region having object species concentration contains supporting substrate which consists of pores, nanoporous layer which is thinner than supporting substrate and liquid transport medium |
| Abstract: An ultra-thin, catalyzed liquid transport medium-based membrane structure fabricated with a porous supporting substrate may be used for separating an object species such as a carbon dioxide object species. Carbon dioxide flux through this membrane structures may be several orders of magnitude higher than traditional polymer membranes with a high selectivity to carbon dioxide. Other gases such as molecular oxygen, molecular hydrogen, and other species including non-gaseous species, for example ionic materials, may be separated using variations to the membrane discussed. |
| Use: A membrane structure for moving object species from first region having object species first concentration. |
| Advantage: Processing stages are removed or modified. |
| Novelty: A membrane structure comprises supporting substrate which consists of pores, nanoporous layer which is thinner than supporting substrate and consists of hydrophilic layer with thickness of ≤ 50 nm and hydrophobic layer, and liquid transport medium which consists of liquideous permeation medium and ≥ 1 catalyst in liquideous permeation medium. |
