| Özet |
| The impacts of titanium dioxide (TiO2) filler on the dielectric response of ionic liquid (IL)-doped sulfonated polyether ether ketone (SPEEK) electrolytes have been investigated. Neat SPEEK, IL-doped SPEEK (SPIL), and IL-doped TiO2-filled SPEEK (SPILTO) composite membranes were prepared with the conventional solution cast method and characterized by various techniques. Fourier-transform infrared (FTIR) spectroscopy analyses confirmed the sulfonation and also showed the dispersion of imidazole and TiO2. Thermogravimetric analysis (TGA) results showed that all composites are thermally stable to comply with electrochemical requirements up to nearly 150 °C. SPILTO-1 composite exhibited a storage modulus of 74 MPa and a glass transition temperature (Tg) of 140 °C. More than 1 wt% TiO2 fillers resulted in heterogeneous membrane surfaces for SPILTO samples. The SPILTO-1 electrolyte showed a … |
