Abstract:
Novel poly(2‐(3‐sulfo)benzoyl‐1,4‐phenylene)‐ block ‐polynaphthalimide (PSP‐ b ‐PI) copolymers were successfully synthesized by Ni(0)‐catalyzed copolymerization of 2,5‐dichloro‐3′‐sulfo‐benzophenone and dichloro‐terminated naphthalimide oligomer. The membranes exhibited a microphase‐separated structure and good hydrolytic stability at 130 °C. They showed a fairly strong anisotropy of membrane swelling with much smaller in‐plane swelling, but a rather weak anisotropy of proton conductivity. The membranes had a fairly high through‐plane conductivity in water and even under low relative humidity. The PSP‐ b ‐PI copolymer with an IEC of 1.5 meq · g −1 showed high PEFC performance due to the high through‐plane conductivity. magnified image
