摘　　要：膦(磷)酸功能化硅氧烷质子交换膜是最有望应用于高温质子交换膜的新材料。综述了膦(磷)酸功能化硅氧烷高温质子交换膜的研究进展,重点讨论了环氧开环、自由基共聚、形成酸碱对以及膦酸酯基硅氧烷水解交联4种不同的将膦(磷)酸键合在杂化膜中的方式,并从物理化学稳定性、电导率等方面比较各种质子交换膜的性能,最后展望了膦(磷)酸功能化硅氧烷高温质子交换膜的发展趋势。Phosphonic （phosphoric）acid functionalized siloxane proton exchange membrane is one of the most promising new materials applied in high-temperature proton exchange membrane.The research progress about phos-phonic （phosphoric）acid functionalized silicone used as high-temperature proton exchange membranes is reviewed, with emphasis on chemically bond phosphonic acid onto hybrid membranes,including epoxy ring opening,free radical copolymerization,acid-base reaction and hydrolysis crosslinking of phosphate functionalized silicas.In addition,vari-ous kinds of proton exchange membranes properties are compared in terms of physical and chemical stability,and elec-trical conductivity,and finally a perspective upon their future development trend is presented.
