Abstract
ZnO and Ag nanoparticle have known their antibacterial activity especially their use in medical materials. In this study, ZnO-Ag Nanocomposite was synthesized by ultrasonication-microwave combination method with variation of reaction time using clove oil as their bioreductor. ZnO-Ag was prepared from ZnO Acetate as a source of ZnO and AgNO3 as a source of Ag. The crystallinity structure, average particle size, morphology, and composition of ZnO-Ag was characterized by X-Ray Diffraction, Scanning Electron Microscope, and Energy Dispersive X-ray Spectroscopy. X-ray diffraction pattern indicates that reaction time of 30 minutes have optimal synthesis results. The nanocomposite obtained consists of 43.2 % Ag nanoparticle, 17.5 % hexagonal Zincite, 14.6% Zinc Oxide, 14.5% wulfingite (deuterated), and 10.2% Zn(OH)2 with average particle size of 28.29 nm according to Scherer’s equation. The result of scanning electron microscope showed that ZnO has an fiber shape and Ag has a round shape.
