The fabrication of ultrathin films and their gas separation performance from polymers of intrinsic microporosity with two-dimensional (2D) and three-dimensional (3D) chain conformations 2019 Access copy available to the general public Unrestricted The expansion of the use of polymeric membranes in gas separation requires the development of membranes based on new polymers with improved properties and their assessment under real operating conditions. In particular, the fabrication of ultrathin films of high performance polymers that can be used as the selective layer in composite membranes will allow large reductions in the amount of the expensive polymer used and, hence, the cost of membrane fabrication. In this contribution, two polymers of intrinsic microporosity (PIMs) with very different chain configurations (two-dimensional, 2D, chains or conventional contorted three-dimensional, 3D, conformation) have been compared in their ability to form ultrathin films, showing the relevance of polymer design to obtain compact and defect-free films. Monolayers of the 2D polymer PIM-TMN-Trip can be efficiently deposited onto poly[1-(trimethylsilyl)-1-propyne] (PTMSP) to obtain composite membranes with a CO2/N2 selectivity similar to that of the corresponding thick membranes of the same PIM using only a small fraction of the selective polymer (less than 0.1%). info:eu-repo/grantAgreement/ES/DGA/E31-17R info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/EC/FP7/608490/EU/Energy efficient MOF-based Mixed Matrix Membranes for CO2 Capture/M4CO2 info:eu-repo/grantAgreement/ES/MEC/FPU2014 info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-77290-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.489 2019 1.45 2019 CHEMISTRY, PHYSICAL 31 / 158 = 0.196 2019 Q1 T1 Biomaterials 2019 Q1 Surfaces, Coatings and Films 2019 Q1 Electronic, Optical and Magnetic Materials 2019 Q1 Colloid and Surface Chemistry 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Vidal, J.
