| 1. | The liquid uptake of polymer electrolyte membrane first increase , then remaining the same as the increasing of ratio of solvents . mechanism capability and ionic conductivity fist increase then decrease during the process , but it changed not much in total . through the test of sem it can be found that the structure of membrane changed little during the process
在增塑剂含量及聚合物基质含量一定的条件下,随溶剂含量的增大,聚合物膜的吸液率先增大后基本保持不变,机械强度及离子电导率则先增大后减小,通过sem测试可知,膜的表面形貌无明显变化。 |
