| 摘 要： | 利用溶胶-凝胶法制备出了SPPO/SiO2/PWA复合质子交换膜,对膜的离子交换容量(IEC)、平均当量重量(EW)、磺化度(SD)、吸水性、溶胀率、质子电导率、Tg进行了表征,此外,还对膜的结构进行了FT-IR、SEM表征,结果表明,所制得的掺杂2%～5%SiO2和3%PWA的SPPO复合膜在100℃、100%相对湿度时的质子电导率与Nafion-117?膜相近,有望作为质子交换膜使用。

| Abstract: | SPPO/SiO2/PWA composite proton exchange membranes ware prepared through sol-gol process,The ionic exchange capacity(IEC),equivalent weight(EW),sulfonation degree(SD),water uptake,expansion ratio,proton conductivity and Tg of the membranes were investigated,and their structural properties ware characterised.The results indicated that the proton conductivity of the membrane doped with 2%-5% SiO2 and 3%PWA was closed to that of Nafion-117 at 100℃ andat 100% relative humidity.The membrane can be as a candidate of proton exchange membrane. |
