The improvement of mixed matrix membranes performance via introducting Ionic Liquids

The effect of ionic liquids on the gas permeation properties of polyurethane- ZnO nanoparticle mixed matrix membranes was investigated. Ionic liquid and commercially ZnO nanoparticles were used as fillers and the membranes were prepared by casting-evaporation method. The structural characteristics of the membranes were studied by Fourier Transform Infrared spectrometer (FT-IR), Field Emission Scanning Electron Microscopy (FESEM) and thermal gravimetric analysis (TGA) to confirm some interaction between the PU and IL and nanoparticles and the changes induced in PU micro phase in the presence of ZnO, IL. Also the transport performances of carbon dioxide (CO2), methane (CH4) and nitrogen (N2) were investigated. Our results showed that the RTIL component may have served as an interfacial material for better adhesion between the inorganic ZnO surface and organic polymer.
