Abstract:
In order to improve the proton conductivity and dimensional stability of proton exchange membranes derived from sulfonated poly( arylene ether sulfone) s( SPAES) ,a series of N( or T) -type SPAES blend membranes are prepared. The blending method is proposed, and sodium salt form( or triethylamine salt form) SPAES with different ion exchange capacities( IEC) are used. The dimensional changes in the in-plane and through-plane direction of blend membranes are obtained from a test. The proton conductivities of blend membranes in the in-plane are tested by electrochemical impedance spectroscopy. The results show that the T-type blend membranes have better intermiscibility than the N-type ones. The dimensional stabilities of both types of blend membranes are enhanced. The T50 blend membrane( IEC=2. 07 meq /g) exhibits dimensional changes of 0. 14 and 0. 15 in the in-plane and through-plane direction in the water of 30 ℃. The blend membranes show comparable proton con ductivities( 8 ~ 274 mS /cm) with pure SPAES membranes around 30% ~ 100% relative humidity at 60 ℃.
