Method for making a composite polyamide membrane |
摘要 |
<p>A method for making a composite polyamide membrane comprising the steps of applying a polyfunctional amine monomer and polyfunctional acyl halide monomer to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is includes at least one of the following steps: i) conducting the interfacial polymerization in the presence of a C2-C20 aliphatic monomer comprising at least one carboxylic acid functional group or salt thereof, and a single amine-reactive functional group; and ii) applying a C2-C20 aliphatic monomer comprising at least one carboxylic acid functional group or salt thereof, and a single amine-reactive functional group to the thin film polyamide layer. Many additional embodiments are described including applications for such membranes.</p> |
