摘要
在聚乙烯醇(PVA)中添加磷钨酸(PWA)和氧化铝(A l2O3),制得复合质子交换膜,测定其电导率、含水率、溶胀度和甲醇透过系数等性质.研究表明,该复合膜兼具较佳的导电率和较好的阻醇效果.
Composite proton exchange membranes are prepared with polyvinyl alcohol (PVA), phosphotungstic acid (PWA) and alumina (Al203). The proton conductivity, water uptake, swelling degree and methanol permeability of the membranes are measured. The composite membranes have both excellent proton conductivity and good barrier property for methanol.
