A proton conducting composite membranes were prepared by solution casting method, form poly(styrene-ethylene-butylene-styrene) (SEBS) solution with SiO2 and nanoclay. poly(styrene-ethylene-butylene-styrene) composite membranes were sulfonated chlorosulfuric acid(CSA) as a sulfonation agent at room temperature by immersing method. The fabricated composite membranes were characterized in detail in this study. The proton conductivity of the fabricated membranes were measured by AC impedance analyzer, the structural properties were examined by AFM and FT-IR spectroscopy, and thermal stability was studied by TGA. |
