摘要

采用嵌段共聚制备了具有不同链段长度的非磺化/磺化多嵌段型磺化聚芳醚砜阳离子交换膜（bSPAES），研究了bSPAES膜在微生物燃料电池（MFC）作为分离膜的性能. 由于在亲水磺化部分引入了刚性更强的芴结构，bSPAES膜表现了更好的尺寸稳定性和水解稳定性. 链段长度控制在10~30的bSPAES膜在30 ℃水中的尺寸变化表现为各向同性，介于10%~20%之间. bSPAES膜的质子导电率为81~140 mS/cm，远超过商用的ULTREX CMI-7000.经过1000 h MFC 运行后，bSPAES膜电导率几乎没有发生降低. 100 ℃ 24 h高温水稳定性试验表明，bSPAES膜的失重率仅在1.5%~6.3%之间. MFC最大功率密度也随着bSPAES中链段长度的增加而提高，链段长度为15~30的bSPAES膜的MFC产电性能优于商用ULTREX CMI-7000膜，bSPAES（30/30）膜在MFC中的最大功率密度达到705 mW/m2.

Abstract

A series of cation exchange membranes based on multiblock suflonated poly(arylene ether sulfone)s (bSPAES) were prepared successfully and used as the separators in the microbial fuel cell (MFC) systems.The properties of the membranes relative to the MFC applications were investigated in details.After introduction of the rigid fluorenyl in the hydrophilic moieties of bSPAES

the corresponding membranes exhibited much better dimensional stability and hydrolytic stability.bSPAES showed isotropic performance in a range of 10%~20% in size change and 81~140 mS/cm of proton conductivity

which were much higher than those of commercial product of ULTREX CMI-7000.After 1000 h MFC operation

almost no changes were observed for the proton conductivity of bSPAES membranes.Hydrolytic stability test in 100 ℃ water for 24 h showed that the weight loss was between 1.5% and 6.3%.The maximum power density of MFC increased with the block length increasing.Comparing with the ULTREX CMI-7000 membrane

the bSPAES membranes exhibited much higher MFC performances

and the maximum power density for bSPAES(30/30) reached to 705 mW/m2.
