Living radical polymerization of fluorine vinyl monomer using long-term radicals in solid state and application of fuel cell membrane.

为了合成可应用于汽车移动的电力燃料电池以及家用热电联产系统的聚合物电解质膜（PEM），辐射接枝聚合是一种将具有质子导电性的接枝链直接引入氟聚合物的简便方法。将氟乙烯基单体引入聚合物膜中，既可利用辐照接枝聚合的长时程自由基，又可利用活性自由基聚合的稳定自由基，可获得上级耐久性优异的PEM。

For synthesis of polymer electrolyte membrane (PEM) that can be applied to fuel cells for mobile electricity in vehicles, as well as a domestic co-generation system, radiation-induced graft polymerization is a convenient method to introduce directly graft chains with proton conductivity into fluorine polymer. A superior durable PEM which introduced fluorine vinyl monomer into polymer films can be obtained by using both long-term radicals by irradiation for graft polymerization and stable radicals for living radical polymerization.
