Hydrothermal Synthesis of Polystyrene-ZnS Core Shell Nanoparticles

In this paper, synthesis of Polystyrene-ZnS core-shell nanoparticles in the presence of anionic surfactant and poly (vinyl pyrrolidone) (PVP) have been investigated. The hydrothermal method results in the formation of sphallerite phase on the surface of polystyrene. SEM images indicate that using different amount of surfactant, the size of core-shell particle changes from 400-700 nm to 70-100 nm. FTIR spectra reveal complete coverage of polystyrene surface by ZnS shell. The broadening of different ZnS diffraction peaks can be related to crystallite size and the degree of crystallinity decrease with increasing of surfactant content.
