The CO2 permeability of the best performing fresh MMM (containing 0.05 wt% GO-POSS) was ~ 12000 Barrer, which is 69% higher than that of the neat PIM-1 membrane, with about the same selectivity (CO2/CH4 selectivity ~ 12 and CO2/N2 selectivity ~ 20). In both cases, the gas separation data surpass the 2008 Robeson upper bound. In addition to the initial CO2 permeability enhancement, the use of GO-POSS is an efficient strategy to slow down physical aging. The MMM at a filler loading of 0.75 wt% showed less than half of the reduction in CO2 permeability than the neat PIM-1 membrane 160 days after preparation (26% for the MMM vs 58% for the purely polymeric one). © 2022 The Author(s) 000118806 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/RYC2019-027060-I 000118806 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000118806 590__ $$a8.6$$b2022 000118806 592__ $$a1.339$$b2022 000118806 591__ $$aENGINEERING, CHEMICAL$$b12 / 141 = 0.085$$c2022$$dQ1$$eT1 000118806 593__ $$aFiltration and Separation$$c2022$$dQ1 000118806 593__ $$aAnalytical Chemistry$$c2022$$dQ1 000118806 594__ $$a12.7$$b2022 000118806 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000118806 700__ $$aAmeen, A.
