The synthesis and characterization of a series of novel acid monomers based on sulfonimides with different acidities are described. Copolymerization of the acid monomers with acrylonitrile was carried out, and the proton exchange membranes were cast from solutions of the resulting copolymers. Flexible, mechanically strong, and transparent membranes with different equivalent weights could be prepared
描述了基于具有不同酸度的磺酰亚胺的一系列新型酸单体的合成和表征。进行酸单体与丙烯腈的共聚,并从所得共聚物的溶液流延质子交换膜。可以制备具有不同当量的柔性,机械强度高且透明的膜。与较低的当量重量和较低的酸度相比,较低的当量重量和较高的酸度的膜在加湿条件下表现出较高的质子传导性。膜电极组件是使用合成的磺酰亚胺共聚物制造的。H 2 / O 2 在单个电池中测试了燃料电池的性能,这揭示了磺酰亚胺膜对聚合物电解质燃料电池的潜在适用性。
