| titleOfInvention | A kind of sulfonated perfluorocarbon cyclobutyl polyarylether polymer and its preparation method and application |
| abstract | The invention discloses a kind of sulfonated perfluorocarbon cyclobutyl polyarylether polymer and its preparation method and application, belong to field of fuel cell technology.With different methoxyl group fragrance dihydric phenols and 1,2 dibromotetrafluoroethanes it is raw material in the present invention, prepares the Trifluorovinyl Aryl Ethers monomer containing methoxyl group；The polymerization of (π of 2 π+2) thermal cyclization is utilized, obtains the perfluorocyclobutanearyl polyarylether polymer containing methoxyl group；Itself and Boron tribromide are acted on, protection ylmethyl is removed, prepares the perfluorocyclobutanearyl polyarylether polymer with different hydroxy radical contents；Using the method for grafting, sulfonation side base is introduced, sulfonated perfluorocarbon cyclobutyl polyarylether polymer is obtained, for preparing PEM.The weightless temperature for the sulfonated perfluorocarbon cyclobutyl polyarylether polymer 5% that the present invention obtains can be to more than 217 DEG C；With low water absorption rate, swelling ratio；Proton conductivity is high, can be as the proton exchange membrane material of fuel cell. |
