Abstract
The present invention relates to a COselective gas separation membrane and a method for preparing the gas separation membrane and the use thereof. The COselective gas separation membrane comprises a gas permeable or porous support layer; and at least one gas permeable polymer layer, which is surface modified with polymer chains having COphilic groups, wherein the gas permeable polymer layer has a spatially controlled distribution of the COphilic groups on the surface thereof. The method of preparing the COselective gas separation membrane, comprises the steps of: depositing at least one gas permeable polymer layer on a porous or gas permeable support layer to form a dense membrane, and surface modifying the dense membrane with polymer chains having COphilic groups, to obtain spatially controlled distribution of the COphilic groups on the surface thereof.
