     in this work, solvent blending in combination with extruding are applied to provide polystyrene/silica nanocomposite specimens. transmission electron microscope (tem) and scanning electron microscope (sem) show same nanoparticle dispersion in ps matrix in low to high filler loadings. differential scanning calorimetry (dsc), dynamic mechanical thermal analyzer (dmta) and thermogravimetric analyzer (tga) were used to study the thermophysical characteristic of the nanocomposites in solid state. in addition, the melt state rheological behavior of the samples was investigated under constant and zero shear rates. interestingly, different behaviors were detected in nanocomposites in low and high nanoparticle loadings. in addition, rheological characteristics of molten polymer are dramatically affected in samples with low nanosilica concentration while stabilized in high filler loadings.
