    Enhanced hydrolytic stability of sulfonated polyimide ionomers using bis(naphthalic anhydrides) with low electron affinity
    摘要:
    为了寻求水解稳定的磺化聚酰亚胺(SPI)膜作为质子交换膜的候选材料,并在高温下使用、制备了一系列基于低电子亲和力双(萘酐)的新型 SPI 离聚物,即 4,4′-硫化双(萘酐)(SBNA)和二苯甲酮-4,4′-双(4-硫代-1,8-萘酐)(BPBTNA)。尽管这些聚合物的固有粘度在 0.41 至 0.59 dL g-1 之间,但它们还是获得了坚韧、柔韧和透明的膜。SPI 膜具有良好的热稳定性,磺酸基的分解温度超过 300 °C,并具有良好的机械性能,在 25 °C、50% 相对湿度条件下拉伸强度为 65 兆帕。SPI 膜的质子传导性随温度和离子交换能力(IEC)的增加而增加,在 100% 相对湿度条件下,IEC 为 2.23 mequiv. g-1 的 S-O(80)膜的质子传导性高于 Nafion® 212。对高 IEC 膜进行的显微分析表明,亲水团簇分散良好且相互连接。加速水稳定性测试表明,基于 SBNA 和 BPBTNA 的 SPI 离聚物在 140 °C 的水中老化 24 小时后仍能保持较高的机械强度,这比基于 1,4,5,8-萘四羧酸二酐(NTDA)的 SPI 膜要稳定得多。聚合物水解稳定性的提高与理论计算得出的二酐电子亲和力(Ea)结果密切相关。这项研究表明,这种策略将有利于进一步开发适用于高温 PEFC 的水解稳定性 SPI。

    In the pursuit of hydrolytically stable sulfonated polyimide (SPI) membranes as promising candidates for proton exchange membranes, usable at elevated temperature, a series of novel SPI ionomers based on the low electron affinity bis(naphthalic anhydrides), 4,4′-sulfide-bis(naphthalic anhydride) (SBNA) and benzophenone-4,4′-bis(4-thio-1,8-naphthalic anhydride) (BPBTNA), were prepared. Tough, flexible, and transparent membranes were obtained from these polymers, although their inherent viscosities ranged from 0.41 to 0.59 dL g−1. The SPI membranes were thermally stable with the decomposition of sulfonic acid groups over 300 °C, and exhibited good mechanical properties with 65 MPa of tensile strength at 25 °C and 50% RH. The proton conductivities of the SPI membranes increases with increasing temperature and ion exchange capability (IEC), and the S–O(80) with 2.23 mequiv. g−1 of IEC showed a higher proton conductivity than Nafion® 212 at 100% RH. For the high IEC membranes, microscopic analyses revealed the hydrophilic clusters were well-dispersed and connected to each other. The accelerated water stability tests demonstrated that the SPI ionomers based on SBNA and BPBTNA maintained a high mechanical strength after being aged in water for 24 h at 140 °C, which was much more stable than the SPI membranes based on 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTDA). The improved hydrolytic stability of polymers could be well correlated with the results of the electron affinity (Ea) of the dianhydride calculated by the theoretical calculation. This investigation illustrated that this strategy will benefit the further development of hydrolytically stable SPIs applied to high temperature PEFCs.
