Abstract
The invention relates to dense synthetic membranes made from polymerised phosphonium-based ionic liquids which were found to be particularly suitable for use in gas separation. The membranes are obtainable by copolymerization via UV-curing of a composition comprising a phosphonium-based ionic liquid monomer, a co-monomer, a cross-linker, a surfactant and a photo-initiator, the remainder of the polymerization mixture consisting of water. The invention also relates to a process of manufacturing said membranes, resulting in solid, dense and mechanically stable membranes, and to the use of the membranes so produced in the separation of gas mixtures, particularly gas mixtures containing carbon dioxide.
