摘要：
In this study, a series of sulfonic-functionalized mesoporous silica (SMS) were synthesized and SMS-Nafion composites membranes were fabricated. The morphology of SMS was characterized by scanning electron microscopy and BET. The physical properties of SMS and composites membranes were tested in terms of ion-exchange capacity, linear expansion, and ionic conductivity. The results showed that the morphology of SMS influenced their physical properties as well as the properties of SMS-Nafion composite membranes.
