## 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)
A novel anion exchange membrane has been prepared using polystyrene-block-poly(ethylene-ranbutylene)-block-polystyrene (SEBS) as a starting material. Chloromethyl groups are first introduced into the SEBS and then converted into the quaternary ammonium groups. The membrane is characterized by Fourie
