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.

The f-MWCNT/GO nanohybrid is integrated into the PLA membrane matrix to form the positively charged mixed matrix membrane. A negatively charged multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) nanohybrid-based mixed matrix membrane can comprise a positively charged Graphene Oxide and negatively charged multi-walled carbon nanotube-COOH (f-GO/MWCNTs-COOH) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-GO/MWCNTs-COOH nanohybrid is integrated into the PLA membrane matrix to form the negatively charged mixed matrix membrane.

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： Disclosed is a desalination method of ion micro-nano sieving for agricultural water in the field of water purification. By constructing a desalting membrane with a composite water channel, through the identification of ion diameter and charge, with fluid dynamics and micro-nano flow theory, the targeted passage of water and salt is realized, and cations like sodium, calcium, magnesium, and anions like chlorine, sulfate, bicarbonate in saline-alkali water are effectively removed, which achieves forward hydrodynamic desalination.
