Sulfonated poly(ether ether ketone) (SPEEK) membranes were used as support material for Nafion-SPEEK-Nafion (NSN) composite membranes. The NSN composite membrane was prepared by immersing the SPEEK in the Nafion-containing casting solution. The resulting composite membranes were mechanically durable
## Abstract This study describes the preparation and characterization of new ionomer blend membranes containing sulfonated poly(ether imide) (SPEI) and poly(ether sulfone) (PES). Thermogravimetric analysis indicated that the obtained blend membranes were more thermally stable than the parent SPEI.
