将膦酸基硅氧烷引入到磺酸基聚2，6-二甲基-1，4-苯醚（SPPO）和咪唑基硅氧烷接枝聚2，6-二甲基-1，4-苯醚（IPPO-Si）中，制备了一系列质子交换膜。以氨基三甲基膦酸（ATMP）和3-氨丙基三乙氧基硅烷（APTES）为原料，合成了膦酸功能化硅氧烷。FTIR结果表明，1-甲基咪唑和APTES成功地接枝到了聚苯醚上，APTES通过水解交联成功地形成了Si-O-Si交联网络。该膜在高达220摄氏度的温度下是热稳定的，并表现出优异的氧化稳定性和机械性能。我们还测量了膜的质子传导率。结果表明，在高温（100 ℃ ~ 160 ℃）和低温（25 ℃ ~ 80 ℃）条件下，随着SPPO含量的增加，复合膜的质子传导率均有不同程度的提高。此外，IPPO-SI-P/SPPO-30具有最好的电导率，在80 ℃，100%RH和160 ℃，5%RH下分别达到0.1131 S cm（-1）和0.1049 S cm（-1）。因此，这种新型膜作为具有更宽适用温度（25摄氏度-160摄氏度）的质子交换膜的潜在候选者。
A series of proton exchange membranes were prepared by incorporating phosphonic functionalized siloxane into sulfonic poly(2,6-dimethyl-1,4-phenyleneoxide) (SPPO) and imidazole functionalized poly(2,6-dimethyl-1,4-phenyleneoxide) grafted with siloxane (IPPO-Si). Phosphonic acid functionalized siloxane was synthesized from amino trimethyl phosphonic acid (ATMP) and (3-aminopropyl)triethoxysilane (APTES). FTIR results showed that 1-methylimidazole and APTES were successfully grafted onto polyphenylene oxide, and APTES successfully formed Si-O-Si crosslinked networks through hydrolytic crosslinking. The membranes were thermally stable up to 220 degrees C and exhibited excellent oxidative stability and mechanical performance. We also measured the proton conductivity of the membranes. The results showed that the proton conductivities of the composite membranes increased with the increasing of SPPO content at different degrees under high (100 degrees C-160 degrees C) and low (25 degrees C-80 degrees C) temperature conditions. Furthermore, the IPPO-SI-P/SPPO-30 has the best conductivity, reaching to 0.1131 S cm(-1) at 80 degrees C, 100%RH and 0.1049 S cm(-1) at 160 degrees C, 5%RH, respectively. Therefore, this novel membrane acts as a potential candidate for proton exchange membranes with a wider applicable temperature (25 degrees C-160 degrees C).
