The electrochemical deposition of sulfonated poly(phenyl ether) (SPPE) from sulfonated phenol precursors was studied by cyclic voltammetry (CV) and chronoamperometry.…
This paper presents the main results obtained during the European project (FCH-JU) "LoLiPEM - Long-life PEM-FCH & CHP systems". The…
Anion exchange membranes (AEM) were prepared by chloromethylation and amination of polysulfone (PSU) and polyphenylsulfone (PPSU). The reaction pathways were…
Anion-conducting ionomers were synthesized by the chloromethylation of polysulfone (PSU) followed by the formation of quaternary ammonium groups by a…
Time-dependent FT-IR spectra of sulfonated poly(ether ether ketone) during dehydration show diminishing 1081 cm−1 and 1023 cm−1 band intensities concurrent with the emergence and…
Ion-exchange membranes based on sulfonated and sulfaminated poly(ether ether ketone) were prepared by a modified sulfamination route. In a first…
The hydration isotherms of various ionomers (Nafion, Sulfonated Poly-Ether-Ether-Ketone, Sulfonated Poly-Phenyl-Sulfone) were measured and described by a thermodynamic model, assuming ideality and a linear relation between…
