Abstract: PURPOSE: The preparation of an organic-inorganic hybrid ion-exchanging membrane is provided to improve the ion conductivity and the ion exchanging capability of the ion-exchanging membrane by blending antimony oxide, styrene-butadiene-styrene, sulfonated polystyrene. CONSTITUTION: Sulfonic acid group substituted polystyrene and styrene-butadiene-styrene are mixed under inert gas. Antimony oxide is added into and mixed with the mixture. The mixture is coated on a base material. A hybrid ion-exchanging membrane is obtained based on a cross-linking reaction at a temperature between 80 and 100 degrees Celsius. The sulfonic acid group substituted polystyrene is obtained by adding polystyrene and sulfonic acid into chloromethane, and a sulfonization process is implemented.
