Abstract:Sulfonated poly (aryl ether ketone)s (SPAEK-A)s were synthesized by 4, 4'-difluorabenzophenone (DFK), sulfonated 4, 4'-difluorabenzophenone (SDFK) and bisphenol A. The structure of SPAEK-A was characterized by FT-IR, and the thermal stability, ion-exchange capacity (IEC), sulfonation degree (D.S.), tensile strength and bending modulus of the polymers were investigated. The results showed that the (SPAEK-A)s have good properties to meet the requirements of the proton exchange membrane.
Keywords:poly (aryl ether ketone)  ion-exchange capacity  the proton conductivity
