Preparation and Characterization of Polyphenylene Anionic Membrane Containing Imidazolium Cation for Fuel Cell Application. |
| 초록 |
The anion exchange polyphenylene membrane containing imidazolium hydroxide ionic functional group was synthesized by sequential chloromethylation, substitution with 1-methylimidazole and ion exchange. The polyphenylene structure of Parmax provides a stiff and resistant backbone, whereas the pendant benzoyl group provides sites for chemical modifications. The resulting ionomer membrane showed ion exchange capacity (IEC) of 2.14 mmol g-1 with maximum chloromethylation yield. The imidazolium-functionalized copolymer membrane showed lower water affinity and excellent chemical stability in alkaline condition. It exhibited hydroxide ion conductivity above 10−2 S cm−1 at room temperature and excellent chemical stability for up to seven days without significant losses of ion conductivity. The structural properties of the synthesized polymer membrane were investigated by 1H NMR spectroscopy and FT-IR. The membranes were studied by IEC, water uptake, and ion conductivity assessment. |
