Enhanced perfluorinated proton membrane containing natural flavonoid organic antioxidant and preparation of enhanced perfluorinated proton membrane

The invention relates to an enhanced perfluorinated proton membrane containing a natural flavonoid organic antioxidant and preparation of the enhanced perfluorinated proton membrane. The enhanced perfluorinated proton membrane comprises a perfluorinated proton membrane layer, a porous polymer supporting layer and the natural flavonoid organic antioxidant dispersed in the perfluorinated proton membrane, the natural organic antioxidant is selected from one or more of rutin, naringenin, naringin, quercetin, baicalin, baicalin, nobiletin, liquiritin, silymarin, daidzein and puerarin. Compared with the prior art, the introduced natural organic antioxidant can effectively scavenge free radicals, and the oxidation resistance and durability of the proton membrane are improved. 本发明涉及一种含天然黄酮类有机抗氧化剂的增强型全氟质子膜及其制备，增强型全氟质子膜包括全氟质子膜层、多孔聚合物支撑层和分散在全氟质子膜中的天然黄酮类有机抗氧化剂，所述的天然有机抗氧化剂选自芦丁、柚皮素、柚皮苷、槲皮素、黄岑素、黄岑苷、陈皮素、甘草苷、水飞蓟素、大豆素、葛根素中的一种或多种。与现有技术相比，本发明引入的天然有机抗氧化剂能有效清除自由基，提高质子膜的抗氧化性和耐久性。
