| 内容記述 | When functionalized by solid-state sulfonation process, the amorphous regions of the semi-crystalline syndiotactic-polystyrene (sPS) become hydrophilic, thus can conduct protons upon membrane hydration, which increases the interest in this material as a potential candidate for applications with proton exchange membranes. The resistance of sulfonated sPS to oxidative decomposition can be improved by doping the membrane with fullerenes. In previous work we have described the morphology in hydrated sulfonated sPS films doped with fullerenes on dif-ferent length scales as determined by small angle neutron scattering (SANS) and the structural changes in such membranes as a function of the degree of hydration and temperature. In the current work we report on the relationship between the morphology of hydrated domains as obtained by SANS and the proton conductivity in sulfonated sPS-fullerene composite mem-branes at different temperature and RH conditions. Based on this combined experimental ap-proach, clear evidence for the formation and evolution of the hydrated domains in functional-ized sPS membranes has been provided and a better understanding of the hydration and conduc-tivity pathways in this material has been obtained. | |||||
