Graft polymer with highly sulfonated side chain and hydrophobic poly(arylene ether sulfone) backbone for polymer electrolyte membrane fuel cell application |
| 초록 |
Graft polymer with highly sulfonated side chain and hydrophobic poly(arylene ether sulfone) backbone has been developed for fuel cell application. The side chain was first synthesized via condensation polymerization with very reactive halogen compound at one end. The synthesized side chain oligomer was then sulfonated with fuming sulfuric acid. The backbone was synthesized via condensation polymerization with hydroxyl groups attached on the side of the rigid polymer. The hydroxyl group reacts with the halogen compound of the side chain when grafted. The structure and the molecular weight of the side chain and the backbone were determined by 1H-NMR. The graft polymer can be synthesized with different variation of ion exchange capacity by controlling the molecular weights of the side chain and the backbone. The graft polymer showed satisfying results in conductivity, dimensional stability, water uptake, and fuel cell performance. |
