SPEEK/BPO4 composite membranes using two types of matrix for fuel cell applications |
| 초록 |
Proton conductive SPEEK/BPO4 composite membranes were prepared by sol-gel process. Tripropylborate and phosphoric acid were used as precursors. The matrix polymers which possess the various degree of sulfonation were obtained by two types of synthesis method. PEEK(Victrex®) was sulfonated using sulfuric acid as sulfonating agent to make post-sulfonated polymers. Pre-sulfonated copolymers were synthesized using sulfonated monomers. The membranes were characterized with proton conductivity, water uptake, ion-exchange capacity, TGA and SEM. SEM micrographs show that the BPO4 particles are homogenously dispersed in the matrix polymers and the BPO4 particle size was greatly influenced with matrix polymer. Pre-sulfonated polymers had much smaller BPO4 particles than the post-sulfonated polymers. |
