"Three novel polyhedral oligosilsesquioxane (POSS) nanofillers functionalized with proton-conducting sulfonic acid groups, mixed sulfonic acid and alkyl groups, and phosphonic acid groups were synthesized, characterized by IR, H-1 and C-13 NMR, and MALDI-TOF MS, and formulated into sulfonated polyphenylsulfone (S-PPSU) carrier polymers. High quality films were cast from 1-methyl-2-pyrrolidinone (NMP), and through-plane and in-plane proton conductivity, mechanical properties, water uptake, dimensional stability, and leaching behavior were measured to assess their suitability for use as hydrogen fuel cell proton exchange membranes," investigators in the United States...
