## Abstract Polymer nanocomposite membranes based on sulfonated poly(ether ether ketone) (SPEEK) (degree of sulfonation 60%) containing varying amounts of open cage trisilanol phenyl polyhedral oligomeric silsesquioxane (POSS) ranging from 0.5 to 5 phr (parts per hundred parts of the polymer resin)
## Abstract The sulfonated poly(ether ether ketone) (SPEEK) / polytetrafluoroethylene (PTFE) composite membranes were produced to aid the swelling properties. The PTFE porous films were used as reinforcing material for the SPEEK/PTFE composite membranes. Scanning electron micrographs showed that SP
Novel multiblock poly(arylene ether sulfone)s were prepared by a two-pot method from a phenoxide-end-capped fully disulfonated poly(arylene ether sulfone) oligomer and a fluoride-end-capped nonsulfonated poly(arylene ether sulfone) oligomer with block length of 10 as the hydrophilic and hydrophobic
A series of cross-linkable sulfonated poly(arylene ether ketone)s bearing carboxylic acid groups (C-SPAEKs) have been prepared for direct methanol fuel cells (DMFCs). The chemical structure of the cross-linkable copolymers was analyzed by 1 H NMR and 13 C NMR spectra. Cross-linked membranes were obt
