Synthesis of Zinc Oxide Nano Rods by Microwave Assisted Precipitation Method Using Polyacrylic Acid

Abstract

A microwave assisted precipitation method has been used for the synthesis of ZnO nanorods by reacting zinc nitrate hexahydrate and sodium hydroxide. Polyacrylic acid (PAA) uses as a polymeric additive in process. The synthesized ZnO is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and laser light scattering technique. It is found that ZnO nanorods exhibit a crystalline structure with hexagonal structure of the wurtzite. Primary size of the synthesized ZnO nanorods can be controlled by PAA concentrations. Increasing of PAA concentrations provide ZnO nanorods with smaller and shorter size.
