Sulfonated polybenzophenone/poly(arylene ether) block copolymers were designed and synthesized via Ni-mediated coupling polymerization. The block copolymers were obtained as high-molecular-weight (Mn = 70-110 kDa, Mw = 150-230 kDa) with low polydispersity index (Mw/Mn = 2.0-2.3). The block copolymer membranes showed well-developed hydrophilic/hydrophobic phase separation and high proton conductivity and low gas permeability. The membrane showed better fuel cell performance and durability compared with those with Nafion, state-of-the-art proton conducting membrane.
磺化聚双苯醚/聚芳醚嵌段共聚物通过镍介导偶联聚合设计和合成。嵌段共聚物为高分子量（Mn=70-110 kDa，Mw=150-230 kDa），具有低多分散指数（Mw/Mn=2.0-2.3）。嵌段共聚物膜具有良好的亲水/疏水相分离和高质子电导率以及低气体渗透性。与作为最先进质子传导膜的 Nafion 相比，该膜表现出更好的燃料电池性能和耐久性。
