COMPOSITE MEMBRANE, IN PARTICULAR FOR GAS SEPARATION

摘要

The invention relates to a method for producing a membrane, in particular a gas separation membrane, wherein the membrane has a selective separating layer. The method is characterised by the following method steps: a) a polymer solution is produced from at least one ammonium salt and at least one polymer that is compatible with the at least one ammonium salt, b) the polymer solution is cast to obtain a film, and c) the selective separating layer is produced from the film in a further step, preferably by drying. The invention further relates to a membrane, in particular a gas separation membrane, which has a selective separating layer. Moreover the invention relates to the use of at least one ammonium salt and also to the use of a membrane.
