Novel poly(arylene ether ketone)with fluorene pendants were synthesized and then sulfonated into a series of poly(arylene ether ketone)s with sulfonated fluorene pendants using chlorosulfonic acid. The sulfonated polymers were thereafter cast into membranes from their solutions. The properties of the ionic exchange capacity, sulfonation degree,water uptake, mechanical properties, thermal and oxidative stabilities as well as proton conductivities of the membranes were fully investigated. It was found that their proton conductivities increased continuously with increasing testing temperature up to 130 .C at 100 POLYETHERETHERKETONE SULFONATION PROTON CONDUCTIVITY PROTON EXCHANGE MEMBRANE https://drive.google.com/file/d/15a8-hILSmSzeN-0u_KjxUZSdvbtBLs0f/view?usp=drivesdk https://drive.google.com/file/d/15a8-hILSmSzeN-0u_KjxUZSdvbtBLs0f/view?usp=drivesdk 250602 20260521091123.0
