  Synthesis and ATRP of novel fluorinated aromatic monomer with pendant sulfonate group

  摘要：

  Novel, fluorinated monomer with pendant sulfonate group was synthesized utilizing a two-step derivatization of 2,3,4,5,6-pentafluorostyrene (FS). The first step was a nucleophilic substitution of the fluorine atom in para position by hydroxyl group followed by sulfopropylation. The monomer was polymerized under aqueous ATRP conditions to yield phenyl-fluorinated aromatic homopolymer bearing pendant sulfonates on each repeating unit. Furthermore, this polymer was used as macroinitiator for the ATRP of poly(ethylene glycol) methacrylate. The polymers were characterized by H-1 NMR, SEC and FTIR analyses. Their thermal properties were evaluated by differential scanning calorimetry and thermal gravimetric analyses. (C) 2013 Elsevier B.V. All rights reserved.

  Proton-conducting, fluorinated polymer grafted particles for use in the preparation of catalytic layers for fuel cells, such as H2/air cells or H2/O2 cells. The grafted particles include a particle made of a material for catalyzing oxygen reduction or hydrogen oxidation, such as a platinum particle, that has been grafted with a proton-conducting, fluorinated polymer graft. The proton-conducting, fluorinated polymer graft includes an organic spacer group, a single bond or an organic spacer group, a repeating unit resulting from polymerization of a fluorinated styrenic monomer, and a repeating unit resulting, from polymerization of a non-fluorinated styrenic monomer bearing at least one proton-conducting group.

  用于制备燃料电池催化层的质子传导氟化聚合物接枝颗粒，如H2/空气电池或H2/O2电池。接枝颗粒包括由催化氧还原或氢氧化的材料（如铂颗粒）制成的颗粒，该颗粒已与质子传导氟化聚合物接枝。质子传导氟化聚合物接枝包括有机间隔基、单键或有机间隔基、由氟化苯乙烯单体聚合产生的重复单元以及由带有至少一个质子传导基团的非氟化苯乙烯单体聚合产生的重复单元。
