Ultrasonic synthesis of ZnO nanorods for coating and pigment applications

Zinc oxide is a multifunctional material due to its unique physical and chemical properties. The most important methods of preparation of ZnO is sonochemical method in which ZnO can occur in one- (1D), two- (2D), and three-dimensional (3D) structures on usage of different ways. In this article irradiation of ultrasonic homogenizer are used during synthesis of ZnO with one-dimensional structures, including nanorods. Scanning Electron Microscopy (SEM) images shows the ZnO nanorods that have been exposed under ultrasonic irradiation are quite uniform and homogeneous in structure. The X-ray diffraction pattern (XRD) admits that ZnO synthesized under ultrasonic irradiation results ZnO with highly uniform and preferred orientation along [101]. Uniformity of nanorods can make more effective use of nanocomposites in corrosion control and protection surface.
