| In this paper, preparation and characterisation of Polystyrene-ZnO hybrid nanoparticles are reported. These composite nanoparticles are prepared by two steps method in which first step consists of preparation of the functionalised core polystyrene particles and second step is the deposition of ZnO nanoparticles on the surface of prepared polystyrene core particles. The procedure gives possibility to obtain composite particles with core-shell morphology, where both core size and ZnO shell thickness can be varied by changing the reaction parameters. Effect of NaOH concentration and polymeric core size, on the thickness of inorganic shell and morphology of resulting hybrid nanoparticles is investigated. Morphology of polymeric composite particles is characterised by SEM and ZnO content is determined by TGA. Presence of ZnO nanoparticles on the surface of hybrid nanoparticles is confirmed by XPS. |
