ORGANIC-INORGANIC COMPOSITE COMPOSITIONS, PREPARATION METHODS THEREOF, WATER TREATMENT MEMBRANES AND WATER TREATMENT MODULES COMPRISING THE SAME

摘要

PURPOSE: An organic-inorganic complex composition, a manufacturing method thereof, a water treatment separation film, and a water treatment module are provided to maintain the separation property including the penetration property at the low operating pressure. CONSTITUTION: An organic-inorganic complex composition contains a base resin, and sulfated metal oxide-containing silica matrix dispersed inside the base resin. A manufacturing method of the organic-inorganic complex composition comprises the following steps: and forming the sulfated metal oxide-containing silica matrix; mixing the sulfated metal oxide-containing silica matrix with the base resin. A water treatment separation film includes an organic-inorganic complex film formed with the organic-inorganic complex composition on one side, and a supporter.
