摘　　要：采用纳米原位复合技术制备了Nafion/SiO^2复合膜,TG—DSC(热失重-差热)分析表明Nafion1135/SiO^2复合膜比Nafion1135膜具有较高的含水和保水能力;溶胀率测试表明Nafion1135/SiO^2复合膜能明显降低膜的溶胀形变,其形变能力只有Nafion1135膜的1/4;110℃时,Nafion1135/SiO^2复合膜的电阻率只有Nafion1135膜的1/2。Nation/SiO2 composite membrane were produced via the in situ nano technology,the TG-DSC analyse showed that the Nation 1135/SiO2 composite membrane had higher hydrous content and water-retaining ability than Nation 1135 membrane,after soaking in water,the swelling transfiguration ofNation1135/SIO2 composite membrane only had 25% that of Nation1135 membrane,when 110℃, the resistivity of Nafion1135/SiO2 composite membrane only had 50% that ofNafion1135 membrane.
