ASYMMETRIC COMPOSITE MEMBRANE OF SILICONE POLYMER AND PREPARING METHOD OF THE SAME

摘要

PURPOSE: A manufacturing method of silicon polymer asymmetric composite film is provided to enhance fabrication efficiency, heat resistance and intensity by having inorganic film characteristic and to improve water transmission property. CONSTITUTION: A manufacturing method of silicon polymer asymmetric composite film comprises the following steps: coating a supporter with a macromolecular solution which includes silicon polymer and pore-forming agent; and forming an asymmetrical composite film by phase transfer the supporter by dipping the same into non-solvent. The silicon polymer is ladder type polysilsesquioxanes.
