Gas permeation parameters of mixed matrix membranes based on the polymer of intrinsic microporosity PIM-1 and the zeolitic imidazolate framework ZIF-8

Original language description

Mixed matrix membranes (MMMs) based on the polymer of intrinsic microporosity PIM-1and the zeolitic imidazolate framework ZIF-8 were prepared and their permeation and sorption properties investigated. Self-supported films with ZIF-8 contents up to 43 vol% were studied using GC gas permeation apparatus and a McBain sorption microbalance. Permeability coefficients were determined for the following set of gases:He,H2, O2, N2, CO2, CH4. For ??as-cast?? films, an increase in ZIF-8 loading results in increases in the permeability and diffusion coefficients as well as in the separation factors a(H2/N2), a(H2/CH4), a(He/N2), a(O2/N2) and a(CO2/CH4). For all ZIF-8 contents studied, permeability is enhanced by treatment with ethanol. Data points on several Robeson diagrams are located above the 2008 upper bound. Free volume in MMMs containing ZIF-8 was studied using positron annihilation life time spectroscopy (PALS) and radiothermoluminescence (RTL) methods. It was shown that the introduction
