Abstract
The present invention provides a method for producing a composite solid polymer electrolyte (SPE), which comprises: flushing a membrane with sulfuric acid and drying the membrane to perform sulfonation reaction and obtaining a sulfonated membrane; repeating the above-mentioned flushing and drying process; mixing a first polymer solution with a hydrolyzed and neutralized second polymer solution to obtain a blended polymer solution; mounting the sulfonated membrane in the blended polymer solution and sequentially adding a cross-linking agent and an initiator into the solution to perform a polymerization reaction; and laying the sulfonated membrane completed with polymerization and blended with polymer solution on a flat plate for drying, thereby obtaining a composite solid polymer electrolyte (SPE). Thus, the invented method can produce a composite SPE with high ion conductivity and high mechanical strength.
