Upon proper characterization of the materials by X-ray diffraction, IR spectroscopy, thermogravimetry and electron microscopy, the obtained membranes were tested in gas separation experiments with a 15:85 CO2/N2 mixture. These experiments proved that the ZIF-8 layer prevented from the penetration of the polymer selective film into the SWCNT-bp support, giving rise to a highly permeable selective membrane. The optimum membrane was achieved by the spin-coating method, with better permeation results than that prepared by the phase inversion method, obtaining a CO2 permeance of 566 GPU together with a CO2/N2 selectivity of 20.9. info:eu-repo/grantAgreement/ES/DGA-FSE/T43-20R info:eu-repo/grantAgreement/ES/MCIN-AEI/PID2019-104009RB-I00-AEI-10.13039-501100011033 info:eu-repo/grantAgreement/ES/MICINN/BES-2017-080209 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.3 2023 CHEMISTRY, PHYSICAL 82 / 178 = 0.461 2023 Q2 T2 POLYMER SCIENCE 36 / 95 = 0.379 2023 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 196 / 439 = 0.446 2023 Q2 T2 ENGINEERING, CHEMICAL 70 / 170 = 0.412 2023 Q2 T2 0.551 2023 Chemical Engineering (miscellaneous) 2023 Q2 Process Chemistry and Technology 2023 Q3 Filtration and Separation 2023 Q3 6.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Téllez, Carlos Universidad de Zaragoza (orcid)0000-0002-4954-1188 Coronas, Joaquín Universidad de Zaragoza (orcid)0000-0003-1512-4500 5005 555 Universidad de Zaragoza Dpto.
