Abstract:-
This research studies the relation between viscosity, density, surface tension, optical and microstructure properties of ZnO/waste polystyrene nanoliquid. The nanoliquid prepared by dissolving the waste polystyrene in toluene solvent then mixed with0.1, 0.3, 0.6, 0.9 and 1.2 wt% of ZnO nanoparticles (NPs) using sonication process. Thin film of ZnO/PS is prepared using spin coating device. X-ray diffraction XRD and atomic force microscopy AFM are used to characterize ZnO NPs. Cone-plate viscometer and tensiometer is used to examine the viscosity and surface tension. UV- visible and optical microscopy is used to examine the microstructure and optical properties of the nanoliquid. The results show that the viscosity and density decreases at lower ratio then increased at high ratio of ZnO NPs, while the surface tension increases at lower ration then increases at higher ratio of ZnO NPs. The UV visible shows that the blue shift peak of Plasmon surface resonance at 0.1 of ZnO NPs then red shift increased progressively up to 1.2 of ZnO NPs. The images of optical microscopy indicates lower agglomeration at 0.1 of ZnO NPs as compared with the other ratio. The thermal conductivity increases with NPs concentration increases. There is strong relation obtained between physical and morphological properties of the waste polystyrene nanoliquid. In general from physical properties can predicate the morphological properties and vice versa.
