The present invention relates to the field of polymer chemistry and relates to membranes used as membranes for treating aqueous solutions, for example by reverse osmosis or by microfiltration, ultrafiltration or nanofiltration. It is an object of the present invention to provide a membrane which exhibits a reduced fouling tendency while maintaining or improving filtration properties in the same good condition and provides a simple and economical method for producing such membranes There is. The above object is achieved by a semiconductor device comprising at least one carrier layer, a porous support layer disposed on the carrier layer, an isolation active layer on the support layer, and a cover layer sequentially disposed thereon, wherein the material of the isolation active layer is a carbon- And / or carbon-nitrogen-triple bonds, and wherein the material of the cover layer has at least a functional group which is at least an azide-group, and at least a carbon-carbon- Wherein the functional groups having a carbon-nitrogen-triple bond are chemically covalently bonded to the azide groups. |
