Polymer nanocomposites of polystyrene matrix containing 5 wt % of organoswy were prepared using the solution method with sonication 23 hours. CPBr is used to modify the SWY clay after suturing with surface with Na+. Polystyrene was synthesized through solution polymerization in the presence of potassium persulfate (KPS) as an initiator. The synthesized PS/oswy were characterized by XRD, FTIR, SEM methods. Frequency dependent complex dielectric function, loss tangent spectra of PS and PS/swy nanocomposites up to 5 wt %.The nanocomposite materials with low dielectric constant and loss tang compared to the pure polystyrene were obtained. The dielectric constant increase with the increase of temperatures.
