[10], Commercial polystyrene (PS) was used instead of polymerization of styrene monomers to obtain PS/silica aerogels nanocomposites. Furthermore, nanofiber structure was obtained by electrospinning. The specific surface area, pore volume and particle size of aerogels, which are 590 m2/g, 1.4 cm3/g and 10 nm, respectively, were determined by BET analysis. Thermal gravimetric analysis indicated that the maximum degradation temperature of PS shifted from 412 to 444 °C when silica aerogels content at 10wt%. Regards to improvement in thermal stability, PS/silica aerogels nanocomposites can be a promising candidate for thermal insulation applications.en-USAttribution-NonCommercial-NoDerivs 3.0 United Stateshttp://creativecommons.org/licenses/by-nc-nd/3.0/us/Silica AerogelPS/Silica NanofibersElectrospinningThermal InsulationconferenceObject
