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 20.9.2023http://zaguan.unizar.es/record/12183910.3390/membranes13010071http://zaguan.unizar.es/record/121839oai:zaguan.unizar.es:121839info:eu-repo/grantAgreement/ES/DGA-FSE/T43-20Rinfo:eu-repo/grantAgreement/ES/MCIN-AEI/PID2019-104009RB-I00-AEI-10.13039-501100011033info:eu-repo/grantAgreement/ES/MICINN/BES-2017-080209Membranes 13, 1 (2023), 71 [12 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
