Measurements Scanning Electron Microscopy (SEM) images of the zinc oxide nanoparticles and the epoxy nanocomposites were obtained using a JSM-JEOL 6390 Scanning Electron Microscope. The JSM-6390 is a high performance, low cost scanning electron microscope with a high resolution of 3nm.
SEM images Zinc oxide nanoparticles. Scanning electron microscope was used to decide size, location and shape of the Zinc oxide nanoparticles. These images demonstrated that zinc oxide nanoparticles are spherical in shape and their sizes are about 30-63nm.
Zinc oxide nanoparticles (ZnO NPs) are among the more prominent versatile and technologically important metal oxide nanoparticles, with applications in …
Fig. 1 XRD graph of ZnO nanoparticles Scanning Electron Microscope (SEM) Analysis The SEM analysis was used to determine the structure of the reaction products that were formed. Fig. 2 SEM images of Zinc Oxide Nanoparticles Thin films of the sample were prepared on a carbon coated copper grid by just dropping a very small amount of the
Apr 29, 2011· Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.
Jul 05, 2011· One of the better-known materials that have been widely used for medical applications is zinc oxide nanoparticles (ZnO-NPs). It is not too far from the truth to say that the ZnO is a magic material because of its wide area of applications and flexibility of preparation in different morphologies with different properties.
size of zinc oxide nanoparticles are measured about 160 nm. Figure 2: SEM image of zinc oxide (ZnO) particles, a) 100 000 x, b) 50 000 x. The SEM micrographs of zinc oxide/silver (Ag/ZnO) powders are given in Figure 3. SEM images were used to evaluate the surface morphology of …

Epoxy resin was conjugated with zinc oxide nanoparticles (ZnO NPs) to prepare antibacterial zinc oxide-epoxy resin (ZnO-ER) composite. The property of ZnO-ER was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and SEM-energy dispersive X-ray spectroscopy (SEM …
May 08, 2018· It has also been demonstrated from SEM and TEM images that zinc oxide nanoparticles first damage the bacterial cell wall, then penetrate, and finally accumulate in the cell membrane. They interfere with metabolic functions of the microbes causing their death.
