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%). 000084200 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E31-17R$$9info:eu-repo/grantAgreement/ES/DGA/FSE$$9info:eu-repo/grantAgreement/EC/FP7/608490/EU/Energy efficient MOF-based Mixed Matrix Membranes for CO2 Capture/M4CO2$$9info:eu-repo/grantAgreement/ES/MEC/FPU2014$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-77290-R 000084200 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000084200 590__ $$a7.489$$b2019 000084200 592__ $$a1.45$$b2019 000084200 591__ $$aCHEMISTRY, PHYSICAL$$b31 / 158 = 0.196$$c2019$$dQ1$$eT1 000084200 593__ $$aBiomaterials$$c2019$$dQ1 000084200 593__ $$aSurfaces, Coatings and Films$$c2019$$dQ1 000084200 593__ $$aElectronic, Optical and Magnetic Materials$$c2019$$dQ1 000084200 593__ $$aColloid and Surface Chemistry$$c2019$$dQ1 000084200 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000084200 700__ $$aVidal, J. 000084200 700__ $$0(orcid)0000-0001-6627-0079$$aSánchez-Laínez, J.$$uUniversidad de Zaragoza 000084200 700__ $$0(orcid)0000-0002-9934-1707$$aZornoza, B. 000084200 700__ $$0(orcid)0000-0002-4954-1188$$aTéllez, C.$$uUniversidad de Zaragoza 000084200 700__ $$0(orcid)0000-0001-9193-3874$$aMartín, S.$$uUniversidad de Zaragoza 000084200 700__ $$aMsayib, K.J. 000084200 700__ $$aComesaña-Gándara, B. 000084200 700__ $$aMcKeown, N.B. 000084200 700__ $$0(orcid)0000-0003-1512-4500$$aCoronas, J.$$uUniversidad de Zaragoza 000084200 700__ $$0(orcid)0000-0002-3492-6456$$aGascón, I.$$uUniversidad de Zaragoza 000084200 7102_ $$15005$$2555$$aUniversidad de Zaragoza$$bDpto.
