Research Progress of High-temperature Proton Exchange Membrane Based on Phosphonic (Phosphoric) Acid Functionalized Siloxane |

| Abstract: | 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. |
