| 제목 | Preparation and characteristics of sulfonated polymer electrolyte membrane |
| 초록 | Hydrocarbon membranes have easy functionalization reactions and can produce membranes with high ion exchange capacity, but have a high volumetric strain and brittle properties due to an increase in moisture content resulting from the introduction of functional groups, so there is a limit in durability. Therefore, in this study, a cation exchange membrane was prepared through a sulfonation reaction using poly(2,6-dimethyl-1,4- phenlyene oxide), which is a polymer with excellent chemical resistance and mechanical properties, while supplementing the disadvantages of the hydrocarbon-based membrane. In addition, their moisture content, ion exchange capacity, electrical resistance, and ionic conductivity were measured, and based on this, the optimum manufacturing conditions of the membrane were identified. This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea Government (NRF-2019R1A2C1089512). |
