Abstract
Polyhedral silsesquioxanes (POSS) will be modified using chloromethylation of aromatic POSS cages. These cages will then be co-cast, using solvent, with chloromethylated polysulfones and subsequently quaternized with monofunctional and difunctional trialkylamines in order to render crosslinked films containing the cage-structures. Subsequent alkalization will form anion exchange membranes with high IEC, high conductivity but low swelling, good chemical resistance against strong acids and bases and good mechanical strength. They will be used as AEMs in direct sodium borohydride/hydrogen peroxide fuel cells.
