Polyelectrolyte/fluorinated polymer interpenetrating polymer networks as fuel cell membrane

Preparation, characterization and properties of PVDF-g-PAMPS/PMMA- co -PAMPS/silica nanoparticle as a new proton exchange nanocomposite membrane

“…Moreover, Ho Choi et al reported synthesis of sulfonated poly(styrene-b-methyl methacrylate) (PS-b-PMMA), and is blended with PVDF [15]. Interpenetrating polymer networks combining poly(2-acryl-amido-2-methyl-1-propane sulfonic acid) (AMPS) copolymerized with a fluorinated cross-linker and a second fluoropolymer-based network were synthesized according to an in-situ synthesis by Delhorbe and co-workers [16]. This paper describes the development of a novel and facile technique to produce PVDF containing pendant sulfonic acid groups by grafting through RAFT polymerization.…”

Effect of a neutral fluorinated network on the properties of a perfluorosulfonic acid ionomer as proton exchange membrane

“…Thus, the fluorinated network reduces the ability of sulfonic acid sites accessible to absorb water. This has been already observed on the association between an AMPS-based polyelectrolyte with a fluorinated polymer in Interpenetrating Polymers Networks (IPN) architecture [34]. This could be explained by the fluorinated chains that are present both in Aquivion ® and in Fluorolink ® MD 700, leading more interactions between polymers.…”

Hydrophobic networks for advanced proton conducting membrane: Synthesis, transport properties and chemical stability

“…The fluorinated single network was synthesized as described in previous publications [19,23]. The ring-opening photo-polymerization of fluorinated DFODDE diepoxide oligomer was photochemically initiated by the strong protonic acid triarylsulfonium hexafluoroantimonate (TASH) ( Figure 1).…”

“…In a previous work, we described synthesis and characterization of a first IPN PEMFC membrane combining a polyelectrolyte network with a neutral fluorinated network. We chose as polyelectrolyte partner a PAMPS network and as neutral partner a fluorinated polymer network based on 2,2,3,3,4,4,5,5,6,6,7,7,-dodecafluoro-1,8-octane diol diglycidyl ether (DFODDE) [19]. Trimethylol propane triglycidyl ether (TMPTGE) was included in the fluorinated network to increase the epoxide concentration and to copolymerize with the fluorinated diepoxide oligomer.…”
