Synthesis and characterization of quaternary ammonium functionalized polyhedral oligomeric silsequioxane/quaternized poly (2,6-dimethyl-1,4-phenylene oxide membranes for alkaline fuel cell applications |
| 초록 |
A series of novel alkaline anion exchange membranes were prepared by incorporating quaternary ammonium functionalized polyhedral oligomeric silsequioxane (QPOSS) into quaternized poly (2,6-dimethyl-1,4-phenylene oxide) (QPPO). The structure of QPOSS was confirmed by structural analysis. The QPOSS nano particles impart additional ion conducting sites and reinforcing the membrane in molecular level. The membranes showed good mechanical and thermal stabilities. Moreover, the membranes were tested for water uptake, ion exchange capacity (IEC) and hydroxyl conductivity with respect to alkaline fuel cell application. The experimental results confirm that the addition of QPOSS has the propensity to improve the performance of the anion exchange membrane significantly. |
