Proton-exchange membranes were synthesised by electron beam irradiation of poly(vinylidenefluoride) (PVDF) films (80 mm) followed by styrene graft polymerisation and sulfonation. Physical and electrochemical properties of the membranes were investigated. The membranes were tested as electrolytes in
Composite membranes formed by sulfonated poly-ether-ether-ketone (SPEEK) and sulfonated and/or silylated poly-phenyl-sulfone ((Si,S)PPSU) were prepared. (Si,S)PPSU was used as anchor phase to reinforce membranes based on SPEEK with high degree of sulfonation, which is proton conducting but morpholog
Sulfonated carbon spheres (SCS) were employed with perfluorinated ionomers as a binder to make proton-conducting electrolyte membranes for polymer electrolyte membrane fuel cells (PEMFC). Hot-pressing produced a symmetric, thin membrane with SCS particles concentrated in the center of the membrane.
## Abstract Novel aromatic sulfonated poly(ether ether sulfone)s (SPEESs) with __tert__‐butyl groups were synthesized by aromatic nucleophilic polycondensation of disodium 3,3′‐disulfonate‐4,4′‐dichlorodiphenylsulfone (SDCDPS), 4,4′‐dichlorodiphenylsulfone (DCDPS), and __tert__‐butylhydroquinone (T
