Preparation and Proton Exchange Properties of GO Grafting modified Cross-linked Membranes

International Journal of Electrochemical Science, 2018
The cross-linked membranes were prepared with DS 68% SPEEK and epoxy resin. Sulfonated graphite oxide was grafted into SPEEK main bonds to study the sulfonic acid groups on the impact of proton exchange properties. Using solartron electrochemical testing

Incorporation of multilayered double hydroxides/sepiolite augments proton conductivity performance in low sulfonated polyether sulfone octyl sulfonamide

Materials for Renewable and Sustainable Energy
Low-sulfonation-level polyether sulfone octyl sulfonamide (LSPSO) was blended with a layered double hydroxides (LDHs, Mg2AlCl)/sepiolite nanostructure clay as a filler to create an electrolyte membrane for fuel cell applications.
