제목 Organic/inorganic hybrid composite membranes based on quaternized poly (2,6-dimethyl-1,4-phenylene oxide)/quaternary ammonium functionalized polyhedral oligomeric silsequioxane (QPPO/QPOSS) for alkaline fuel cell applications
초록 A series of novel anion exchange membranes based on organic-inorganic hybrid composites were prepared by incorporating quaternary ammonium functionalized polyhedral oligomeric silsequioxane (QPOSS) into quaternized poly (2,6-dimethyl-1,4-phenylene oxide) (QPPO). QPOSS was synthesized from octaammonium POSS (OPOSS) using epoxide ring opening polymerization with glycidyltrimethylammoniumchloride and the chemical modification was confirmed by structural analysis. The QPOSS nano particles impart additional ion conducting groups and reinforcing the membrane in molecular level. The mechanical and thermal stability were also investigated. 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 addition of QPOSS has the propensity to improve the performance of the anion exchange membrane significantly.
