In this contribution, composite membranes have been obtained by the successive deposition of approximately 1 nm thick monolayers of a polymer of intrinsic microporosity (PIM) on top of dense membranes of the ultra-permeable poly[1-(trimethylsilyl)-1-propyne] (PTMSP). The ultrathin PIM films (30 nm in thickness) demonstrate CO2 permeance up to seven times higher than dense PIM membranes using only 0.04¿% of the mass of PIM without a significant decrease in CO2/N2 selectivity. info:eu-repo/grantAgreement/ES/MINECO/MAT2016-77290-R info:eu-repo/grantAgreement/EC/FP7/608490/EU/Energy efficient MOF-based Mixed Matrix Membranes for CO2 Capture/M4CO2 info:eu-repo/grantAgreement/ES/DGA/E54 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.411 2017 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 3 / 33 = 0.091 2017 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 24 / 171 = 0.14 2017 Q1 T1 2.538 2017 Chemical Engineering (miscellaneous) 2017 Q1 Materials Science (miscellaneous) 2017 Q1 Environmental Chemistry 2017 Q1 Energy (miscellaneous) 2017 Q1 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-6627-0079 Sánchez-Laínez, Javier Universidad de Zaragoza (orcid)0000-0002-9934-1707 Zornoza, Beatriz (orcid)0000-0001-9193-3874 Martín, Santiago Universidad de Zaragoza Carta, Mariolino Malpass-Evans, Richard (orcid)0000-0002-4954-1188 Téllez, Carlos Universidad de Zaragoza McKeown, Neil B.
