In the present work, the acid–base composite membranes were prepared using highly sulfonated poly(aryl ether ether ketone) (SPEEK) and polybenzimidazole (PBI). The morphology characteristics of composite membranes with different content of PBI were studied in detail by SEM, AFM, SAXS, FT-IR and UV....
