A method for transferring gas molecules from a gaseous medium into a liquid medium or vice versa comprising at least the following steps: a) providing a liquid medium having a surface tension liquid air in the range of from 0.02 N/m to 0.06 N/m, b) providing a gaseous medium, c) providing a membrane on an interface between the liquid medium and the gaseous medium, wherein the membrane comprises i) a carrier substrate with through-going openings having a mean diameter in the range from 0.2 μm to 200 μm, preferably in the range from 1 μm to 50 μm, and ii) a porous superamphiphobic coating layer with openings having a mean diameter in the range from 0.1 μm to 10 μm, which coating layer comprises a surface exhibiting a contact angle of at least 150° with respect to 10 μl sized drops of water and also a contact angle of at least 150° with respect to 10 μl sized drops of liquids having a surface tension of not more than 0.06 N/m, in particular oils, alkanes, and aromatic compounds, which is provided at least on the substrate surface facing the liquid medium, wherein either the liquid medium or the gaseous medium, preferably the gaseous medium, comprises at least one target gas to be transferred and said membrane is permeable for the at least one gas to be transferred and not permeable for the liquid medium due to the superamphiphobic properties of the membrane surface facing the liquid medium with respect to said liquid medium, d) contacting the gaseous medium with the liquid medium via said superamphiphobic layer for a sufficient time to enrich the liquid or gaseous target medium with the at least one gas to be transferred. a) providing a liquid medium having a surface tension liquid air in the range of from 0.02 N/m to 0.06 N/m, b) providing a gaseous medium, c) providing a membrane on an interface between the liquid medium and the gaseous medium, wherein the membrane comprises i) a carrier substrate with through-going openings having a mean diameter in the range from 0.2 μm to 200 μm, preferably in the range from 1 μm to 50 μm, and ii) a porous superamphiphobic coating layer with openings having a mean diameter in the range from 0.1 μm to 10 μm, which coating layer comprises a surface exhibiting a contact angle of at least 150° with respect to 10 μl sized drops of water and also a contact angle of at least 150° with respect to 10 μl sized drops of liquids having a surface tension of not more than 0.06 N/m, in particular oils, alkanes, and aromatic compounds, which is provided at least on the substrate surface facing the liquid medium, wherein either the liquid medium or the gaseous medium, preferably the gaseous medium, comprises at least one target gas to be transferred and said membrane is permeable for the at least one gas to be transferred and not permeable for the liquid medium due to the superamphiphobic properties of the membrane surface facing the liquid medium with respect to said liquid medium, i) a carrier substrate with through-going openings having a mean diameter in the range from 0.2 μm to 200 μm, preferably in the range from 1 μm to 50 μm, and ii) a porous superamphiphobic coating layer with openings having a mean diameter in the range from 0.1 μm to 10 μm, which coating layer comprises a surface exhibiting a contact angle of at least 150° with respect to 10 μl sized drops of water and also a contact angle of at least 150° with respect to 10 μl sized drops of liquids having a surface tension of not more than 0.06 N/m, in particular oils, alkanes, and aromatic compounds, which is provided at least on the substrate surface facing the liquid medium, d) contacting the gaseous medium with the liquid medium via said superamphiphobic layer for a sufficient time to enrich the liquid or gaseous target medium with the at least one gas to be transferred.
