| titleOfInvention | Method for preparing porous asymmetric membrane and porous asymmetric membrane prepared therefrom |
| abstract | The present invention relates to a method for preparing a porous asymmetric membrane that can be controlled in various pore sizes, and to a porous asymmetric membrane prepared therefrom. In the method of preparing a porous asymmetric membrane of the present invention, the hydrophilicity of the membrane is improved by using a sulfonated polysulfone polymer-containing polymer solution, and an atmosphere containing volatile organic solvent vapor on the surface cast by the polymer solution is used by a casting process. By optimizing the exposure conditions upon exposure to the substrate, the porous asymmetric membrane increases in average pore size and can be controlled in a variety of pore sizes, reducing the time and cost of adjusting the desired asymmetric structural design, high permeability, and various pore sizes. Can be. |
