    Abstract
    Thermal annealing, a commonly used procedure for improving the performance of polymeric membranes, is in this work exploited in the presence of a metal-organic framework (MOF) supported layer. MOFs and polymers are materials with a common organic character, suggesting an enhanced affinity between them when used together in membrane separation. Zeolite-like imidazolate frameworks (ZIFs) ZIF-8 and ZIF-93 with sod and rho structures and pore apertures of 0.34 and 0.36 nm, respectively, have been grown inside 356 mm OD co-polyimide P84 hollow fibers by microfluidics, leading to continuous supported membranes. When these membranes were thermally in situ annealed below the glass transition temperature, while monitoring both H-2 and CH4 permeances, the MOF-polymer adhesion was enhanced. Thus the gas separation selectivity increased without any significant reduction in the gas permeance, and H-2/CH4 and CO2/CH4 maximum selectivities of 103 and 18 (ZIF-8) and 101 and 20 (ZIF93) were respectively ...
