Novel partially fluorinated graft block copolymer ionomer as potential proton exchange membrane material

A novel well-defined fluorinated graft block copolymer ionomer consisting of poly(2,2,3,3,3-pentafluoropropyl methacrylate)-block-poly(9-anthrylmethyl methacrylate) backbone and partially sulfonated polystyrene side chains was synthesized using double click reactions (Cu catalyzed Huisgen and Diels-Alder reactions) and postsulfonation reaction.
