A proton-exchange membrane, of polymeric mixture, comprising soluble polymers and sulfonated polymers is described. Soluble polymers are selected from at least polysulfone, polyether sulfone and polyvinylidene fluoride. These sulfonated polymers are selected from at least sulfonated poly (ether ether ketone), sulfonated poly (ketone ether ketone ether), sulfonated poly (phthalazinone ketone ether), sulfonated polyether sulfone, sulfonated polyimides, sulfonated polyphosphazene and sulfonated polybenzimidazole; where the sulfonation degree of the sulfonated polymer is 96 to 118 percent. A method for the preparation of the proton exchange membrane, of polymeric mixture, is also described. |
