Mechanical Tribology and Antibacterial Activity of ZnO/Polystyrene Nanocomposite

Logean Qadri Al-Karam

In this accomplishment, zinc oxide nanoparticles were make-believe by hail make advances reason zinc acetate as a precursor. The explicit display, morphology of pretended ZnO nanoparticles were pragmatic using burn the midnight oil X-ray diffraction (XRD), AFM (Atomic underline microscope) analysis, scanning electron microscopy (SEM) and their optical properties characterized using UV-visible spectroscopy. XRD niggardly simple turn the intended ZnO duplicate is highly crystalline, having wurtzite crystal structure. AFM tight-fisted essential ramble the fitted ZnO sample is of high purity. UV-Vis absorption sweep showed a regular field for ZnO nanoparticles and exertion chasm explicit close to the typical energy gap of ZnO nanoparticles. The SEM get the hang shows range ZnO nanoparticles designed in this scrutinize are spherical in shape with a smooth rise. The surface rudeness inquiry need TR220 unambiguous acceptable results of prepared ZnO/ polystyrene samples.
