Enhancement of Chemical Stability of Sulfonated Polyvinylidene Fluoride Proton‐Conducting Membranes by Ceria Incorporation

open access: yesJournal of Polymer Science, EarlyView.
The chemical stability of SPVDF membranes was examined using Fenton's reagent test. It was found that the chemical stability of membranes was enhanced from around 80% to 96% by integration of ceria in the membranes. The ability of ceria to toggle between the two oxidation states was responsible for this enhancement.
