Investigation of optical and dielectric properties of polyvinyl chloride and polystyrene blends in terahertz regime

Terahertz time domain spectroscopy has been utilized to investigate the optical, dielectric, and electrical properties of polyvinyl chloride (PVC) and polystyrene (PS) blend to highlight their utilization in terahertz technology. These blends prepared by solution casting technique, show a prominent change in these properties as a function of blending ratios. Moreover, the universal dielectric response model has been fitted to real THz conductivity which shows the super-linear behavior indicating the restricted motion of carriers. These results provide a database for the efficient utilization of such blends in THz technology.
