以环氧环己基乙基三甲氧基硅烷（EHTMS）和氨基三亚甲基膦酸（ATMP）为原料，采用溶胶-凝胶法制备了基于膦酸的高温无水质子交换膜。通过FTIR、TG-DSC和XRD对不同膦酸含量的膜的结构和性能进行了广泛的表征。还在不同温度下研究了它们在干燥条件下的质子电导率。结果表明，所制备的膜的质子电导率强烈依赖于温度，在无水条件下，质子电导率范围为20℃时的8.81×10−5Scm−1至140℃时的4.65×10−2Scm−1。这表明温度升高有利于接枝-PO3H2的聚集和质子迁移率的增加。此外，从AFM图像结果证实，膦酸基团的连续分布有利于质子传输通道的形成，可以显着增强膜的质子电导率。
High temperature anhydrous proton exchange membranes based on phosphonic acid were prepared from epoxycyclohexylethyltrimethoxysilane (EHTMS) and amino trimethylene phosphonic acid (ATMP) by sol–gel process. The structures and properties of membranes with different phosphonic acid content were extensively characterized by FTIR, TG-DSC and XRD. Their proton conductivity under dry condition was also investigated under different temperature. The results show that the proton conductivity of the prepared membranes strongly depends on temperature, and the proton conductivity ranges from 8.81 × 10−5S cm−1at 20 °C to 4.65 × 10−2S cm−1at 140 °C under anhydrous condition. It indicates that the increasing temperature is favorable for congregating of the grafted–PO3H2and increasing of the proton mobility. In addition, from the results of AFM images, it was confirmed that the continuous distribution of phosphonic acid groups is favorable for the formation of the proton transport channel, which can significantly enhance the proton conductivity of the membranes.
