AbstractPoly(aryl ether ether ketone) is found to be compatible with poly(aryl ether sulfone) at a blending temperature 310°C. There is a single glass transition temperature (Tg) for various compositions of the blend. The relationship ofTgwith composition obeys Gordon‐Taylor's equation, where the adjustable parameter k is 0.43.

Two N3-substituted imidazoles 1,2-dimethylimidazole and 1-butyl-2-methylimidazole were chosen to functionalize poly(aryl ether ketone), respectively. The generated imidazolium cations could electrostatically react with sulfonate ions of the sulfonated poly(ether ether ketone) forming the ionic crosslinking structure of the membranes.

Poly(vinylbenzyl sulfonic acid)-grafted poly(ether ether ketone) membranes
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2014Abstract In this study, an aromatic hydrocarbon based polymer electrolyte membrane, poly(vinylbenzyl sulfonic acid)-grafted poly(ether ether ketone) (PEEK- g -PVBSA), has been prepared by the simultaneous irradiation grafting of vinylbenzyl chloride (VBC) monomer onto a PEEK film and subsequent sulfonation.

AbstractA series of composite membranes consisting of sulfonated carbon nanotubes (sCNTs) and sulfonated poly(ether sulfone ether ketone ketone) were successfully fabricated via the solution casting method. The chemical structure, as well as the long‐term stability of the sCNTs in different solvents, was investigated by Fourier transform infrared (FTIR)

AbstractPartially Sulfonated Poly(ether ether ketone) (SPEEK) samples were prepared by modification of corresponding poly(ether ether ketone) (PEEK) with concentrated sulfuric acid. Poly(ether sulfone)(PES) was blended into SPEEK to prepare PES/SPEEK blend membranes by solution casting.

Nafion® is a currently used Proton Exchange Membrane (PEM) in Vanadium Redox Flow Batteries (VRB). It is an excellent proton conducting and fully hydrated membrane, but it has a very high cost. In order to reduce the cost of the membrane used in VRB and to reduce the vanadium permeability across the membrane during the operation, sulfonated poly (ether
