Synthesis of ZnO nanorods based on electrospinning technology

Abstract

Abstract A new method for fabrication of ZnO nanorods was reported. ZnO nanorods were synthesized by electrospinning technology and heat treatment with polyvinyl alcohol (PVA) and Zinc acetate as precursor. After heat treatment of ZnO electrospun nanofibers, ZnO nanorods were obtained. Morphology of ZnO nanorods was characterized by Scanning electron microscopy (SEM). Various morphologies, such as sphere, flower and plane composed of ZnO nanorods were observed. Transmission electron microscopy (TEM) images demonstrated ZnO nanorods are a single crystalline structure with a diameter of 100-180 nm. The hexagonal wurtzite structure of ZnO nanorods was determined by X-ray diffraction (XRD) pattern and Raman spectra.
