A photo-crosslinkable aromatic polymer composite membrane is provided to ensure excellent tensile strength and methanol permeability stable to 1/2 level compared with commercial membrane, and to be insoluble in organic solvent. A method for manufacturing a photo-crosslinkable aromatic polymer composite membrane comprises the steps of: synthesizing a photo-crosslinkable ion conductive polymer electrolyte which directly polymerizes a polymer having a repeating unit represented by chemical formula 1; dissolving the polymerized polymer in polar solvent, laminating it between PET films by impregnating a microporous hydrocarbon-based base membrane with the solution and then photocrosslinking and heat-treating it; and charging and photocrosslinking pores of synthetic polymer electrolyte. |
