Dielectric properties of ZnS filled polystyrene nanoparticules

In this paper, zinc sulfide ZnS have been synthesized in reserves cores micelles in PS synthesized by emulsion polymerization. The size and morphology of ZnS/PS particles have been characterized via XRD, TEM, IR, SEM and AFM measurement. The dielectric proprieties of ZnS/PS are synthesized membrane, obtaining a water-swelling percentage around 20% and filled with ZnS nanoparticules were studied as a function of particle coating. The complex permittivity was measured with a 7,600 Meter dielectric spectroscopy analyzer at applied voltage of 1 V with frequency varying between 10Hz and up to 1 KHz at different temperatures measurements are performed in dry conditions.
