The present work deal with the fabrication and characterizations of composite membranes composed of sulfonated poly (ether ether ketone) with polyvinyl alcohol and reinforced with cesium phosphotungstic acid (Cs-HPW), graphene oxide (GO), and silica-carbon nanotube (SCNT). Compared to the blank sPEEK-PVA membrane, the uptake of composite membranes in water varies at around 30-50%, while the swelling ratio is increased. The addition of Cs-HPW, GO, and SCNT reduces the tensile strength and methanol permeability. The ionic exchange capacity slightly varies at around 0.48-0.70 meq/g. From the above studies’ viewpoint, the prepared composite membranes still need to be reviewed so that these membranes are feasible as proton exchange membranes.
