Ionic liquids (ILs) have been used in membrane separation for more than a decade due to their physical and chemical properties, such as non–volatility, thermal stability and ability to dissolve CO2 and a large range of organic molecules. In this paper, we present a new concept in chemically stabilized IL membranes which is an organosilica membrane using a silylated IL as a precursor chemical. The membranes showed selective permeability toward organic vapors against H2 with improved durability over supported IL membranes. Their permeation and separation mechanism, and microstructure were discussed by gas and vapor permeation tests, Attenuated Total Reflection –IR, and N2 adsorption measurements.
