The simultaneous investigation of rheological and dielectric properties, which are called rheo-dielectric , is a method for analyzing the internal structure of nanoparticles in polymer nanocomposites. Combining rheological measurements with dielectric spectroscopy can be very useful to obtain unique information about molecular structure and dynamics and shear-dependent phenomena. Many researches have been done to analyze such properties of nanocomposites using the rheo-dielectric method. In this research, we investigated the effect of dynamic shear strain on the changes in the dielectric properties of PS/TiO2 nanocomposites through rheo-dielectric tests. What we observed was the dramatic changes in the dielectric constant of the nanocomposite compared to its similar pure sample. Also, the dielectric constant decreased with the increase of shear strain at different frequencies.
