Abstract:
A new class of fluorinated and sulfonated block copolymers was synthesized and characterized with respect to morphology using TEM and small angle X-ray and neutron scattering. Proton and methanol transport properties were evaluated with a view toward using these materials for fuel cell membranes. The materials formed microphase separated morphologies, which were generally less well ordered than unfluorinated and sulfonated block copolymers.
