摘要： A CO2 separation membrane can include a CO2-philic layer comprising one or more mobile CO2 carriers and one or more immobile CO2 carriers and a blended CO2-permeable and CO2-selective matrix that hosts the immobile or mobile CO2 carriers and porous nanostructures that adsorb water vapors. The CO2-philic layer can be disposed upstream of the CO2-permeance layer such that a flow of source gas to be separate enters the membrane from a feed side at which the CO2-philic layer is present and CO2 exits the membrane at a permeate side after passing through both the CO2-philic layer and the CO2-permeance layer.

摘要： Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membranes can comprise a support layer, and a selective polymer layer disposed on the support layer. In some cases, the support layer can comprise a gas permeable polymer and hydrophilic additive dispersed within the gas permeable polymer. In some cases, the selective polymer layer can comprise a selective polymer matrix and carbon nanotubes dispersed within the selective polymer matrix. The membranes can exhibit selective permeability to gases. As such, the membranes can be for the selective removal of carbon dioxide and/or hydrogen sulfide from hydrogen and/or nitrogen.

摘要： A single piece-type bipolar film roll with a mesh cloth support and a manufacturing method therefor. The single piece-type bipolar film roll is supported by a high-strength ultra-high molecular weight polyethylene mesh cloth, one side of the single piece-type bipolar film roll is a cation exchange layer containing a benzenesulfonic acid group, the other side of the single piece-type bipolar roll is an anion exchange layer containing a benzyl dimethyl butyl ammonium quaternary amino group, and the middle is a water dissociation catalyst layer containing a benzyl methyl butyl amine tertiary amino group, and the three layers form the single piece-type bipolar film roll. By providing a wider protective film and a narrower spacing film, a dipping and absorbing film roll is polymerized to prepare a composite base film roll which is then subjected to continuous sulfonation to prepare a single-sided sulfonated composite positive film roll, and then the unreacted blank side is sequentially subjected to three-step chemical reactions such as complete chloromethylation, complete tertiary amination and incomplete methylation, so as to prepare a single piece-type bipolar film roll having a compact structure, a clear middle interface, a high mechanical strength and a stable quaternary amino group, and the product qualification rate is high; and the single piece-type bipolar film roll is suitable for a bipolar film electrodialysis engineering application of an organic material-containing system.

The method includes using a gas separation apparatus comprising a selective permeable membrane and a first and second treatment chambers separated by the selective permeable membrane. A mixed gas containing a gas to be separated is supplied into (or generated within) the first treatment chamber, and the gas to be separated is separated from the mixed gas by having the gas to be separated permeate from the first/second treatment chamber side of the selective permeable membrane, which has a stacked laminated structure of a hydrophilic porous membrane, a separation-functional layer, and a first protective membrane, and the separation-functional layer includes a layer of hydrophilic polymer containing water, and the first treatment chamber is provided on a hydrophilic porous membrane side of the selective permeable membrane and the second treatment chamber is provided on the first protective membrane side of the selective permeable membrane.

摘要： Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA extruded layer that enables rapid moisture transfer and exchange through the tube. An extruded composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. An extruded PEBA may be melted into pores of a porous scaffold support. Extruded PEBA may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. A support tube may be configured inside or outside of the PEBA tube.
