摘要： New carbon nanomaterials, preferably titanium carbide-derived carbon (CDC) nanoparticles, were embedded into a polyamide film to give CDC/polyamide mixed matrix membranes by the interfacial polymerization reaction of an aliphatic diamine, e.g., piperazine, and an activated aromatic dicarboxylate, e.g., isophthaloyl chloride, supported on a sulfone-containing polymer, e.g., polysulfone (PSF), layer, which is preferably previously prepared by dry/wet phase inversion. The inventive membranes can separate CO2 (or other gases) from mixtures of CO2 and further gases, esp. CH4, based upon the generally selective nanocomposite layer(s) of CDC/polyamide.

摘要： A method for preparing a super-hydrophobic membrane by cleaning a metal mesh by immersion in an organic solvent; subjecting the cleaned metal mesh to a surface modification treatment to increase its hydrophilicity; coating the treated metal mesh with a hydrophobic organic substance; and drying the metal coated mesh for obtaining the super-hydrophobic membrane. The super-hydrophobic membrane obtained thereby.

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.
