Sulfonated poly[styrene-b-ethylene-co-butylene-b-styrene] (sSEBS) block copolymers/inorganic nanocomposite materials were synthesized via in situ formation of inorganic fillers and characterized particularly for their dielectric properties and proton conductivities.
In preparation of sSEBS/SrTiO3 nanocomposites, titanium (IV) isopropoxide [Ti(OPri)4] complex was diffused into sSEBS film, followed by subsequent hydrolysis of [Ti(OPr i)4], diffusion of strontium cations in sSEBS domains, and in situ formation of crystalline SrTiO3. sSEBS with sulfonation degree of 38.1% and 65.0% were employed, and relevant sSEBS/SrTiO3 composites contain SrTiO3 of 10-15 wt%. Elemental composition characterization with ESEM/EDX indicated uniform distribution of …
