제목 Properties of SEBS/SiO2 and Nanoclay Composite Membranes
초록 A ion conducting polymer membranes were prepared by solution casting method, form poly(styrene-ethylene-butylene-styrene) (SEBS) solution with fumed silica and nanoclay as inorganic fillers. SEBS composite membranes were sulfonated using chlorosulfuric acid as a sulfonation agent at room temperature by immersing method during variety of time periods. The ion conductivity of the fabricated membranes was calculated from resistance that was measured by AC impedance analyzer. The ion conductivity was enhanced with increasing the degree of sulfonation and reached 0.5 S/cm when the silica content was 10wt% at sulfonation time of 5min. The structural properties were examined by AFM and FT-IR spectroscopy. Thermal stability and mechanical properties were studied by TGA and DMA.
