TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The fluorine-containing olefin is selected from tetrafluoroethylene, chlorotrifluoroethylene, trifluoroethylene, hexafluoropropylene or polyvinylidene fluoride, preferably, the fluorine-containing olefin is selected from tetrafluoroethylene or chlorotrifluoroethylene. An azo-evocating agent is also included, which is selected from azobisformamide, azobis-isobutyl cyanide, azobis-isoheptenoic cyanide, azodiisobutyric acid dimethyl ester, 1-((cyano-1-methyl ethyl)azo)methanamide, 1,1'-azo(cyclohexyl-1-cyano), 2,2'-azo(2-methyl propyl amidine)dihydrochloride, 1,1'-azobis(4-cyano-pentanoate), or 3-hydroxyl-4-nitryl benzoic acid. The fluorine-containing olefin monomer with functional radical is selected from compounds having structural formulae (II-VI). A peroxide evocating agent is also used during fluorine-containing ion exchange resin preparation, which is perfluoro-organic peroxide. The fluorine-containing ion exchange resin is selected from sulfuryl fluoride, sulfuryl chloride or sulfuryl bromide resin. The cross-linking agent has structural formulae (VII-VIII).

The cross-linking agent is selected from ammonia, hydrazine, organic diamine or substance that release ammonia or hydrazine.    TECHNOLOGY FOCUS - POLYMERS - Preferred Methods: The membrane is prepared by extrusion, heat pressing, spin coating, casting, screen painting, spray finishing or impregnating technology of solution or melt. The multilayered membrane is prepared by combination between single-layer membranes, combination between single-layer membrane and multilayered membrane or combination between multilayered membrane and multilayered membrane, or prepared by extrusion, heat pressing, spin coating, casting, screen painting technologies, spray finishing or impregnating technology of solution or melt on the prepared single-layer membrane or multilayered membrane.
