摘要
The present invention relates to a method for manufacturing a composite membrane using a selective layer prepared through the interfacial polymerization (support-free interfacial polymerization) on a free interface without a support and, more specifically, to a method for manufacturing a composite membrane comprising a reverse osmotic membrane, which is obtained by preparing a selective layer through a spontaneous reaction of two organic monomers on an interface between two immiscible solutions and allowing the selective layer to adhere to a support. By employing the method for manufacturing a composite membrane having a selective layer prepared through the support-free interfacial polymerization according to the present invention, a high-functional reverse osmotic membrane can be prepared using various supports other than a conventional polysulfone support, thereby extending the application range of the reverse osmotic membrane, which has been restricted due to low chemical resistance of polysulfone. In addition, the preparation method for the selective layer can be controlled more precisely than a conventional method, and the analysis of components (selective layer, support, and interface) of the composite membrane is easy.
