Ion exchange membranes from sulfonated fluorenyl polymers containing fluorinated moieties for fuel cell |
| 초록 |
we report on the preparation and characterization of sulfonated polymer membranes containing fluorinated moieties for polymer electrolytes. The polymers were synthesized through the synthesis of a monomer containing the trifluorovinyloxy group at both ends, thermal polyaddition, and post-sulfonation using chlorosulfonic acid. seven sulfonated polymers with different sulfonation degree (SD) and ion exchange capacity (IEC) were prepared by changing the content of chlorosulfonic acid during the post-sulfonation reaction. As the content of chlorosulfonic acid increased, the SD, IEC, water uptake, and ion conductivity of the sulfonated polymer membranes increased. |
