摘要:
为了提高磺化聚芳醚砜( SPAES) 类质子交换膜的质子导电率及尺寸稳定性,制备了一系 列N 型( 或T 型) SPAES 共混质子交换膜。采用共混方式,利用具有不同离子交换容量( IEC) 的磺 酸钠盐( 或磺酸三乙胺盐) 型SPAES 进行了制备。通过测试得到共混膜的膜面方向及厚度方向的 尺寸变化率。采用电化学阻抗光谱技术测定共混膜在平面方向的质子导电率。结果表明: T 型共 混膜的共混性高于N 型共混膜; 共混膜的尺寸稳定性明显增强,如IEC 为2. 07 meq /g 的T50 共混 膜在30 ℃水中膜平面方向及厚度方向的尺寸变化率仅为0. 14 和0. 15; 共混膜在温度60 ℃相对 湿度30% ~100%下质子导电率( 8 ~247 mS /cm) 与纯SPAES 膜相当。
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 ℃.
