Simulation and ZnO nanowires-based generation of a hierarchical structure on an optical fiber core

A hierarchical structure with a random rough surface superimposed on a cylinder substrate was presented in this paper. The effect of the characteristic parameters on the surface properties of this hierarchical structure was summarized and partially simulated. The hierarchical structure was generated by synthesizing ZnO nanowires with hydrothermal method on an optical fiber core. Scanning electron microscopy (SEM)-based characterization of the generated random rough surface on the optical fiber core was employed to regulate and optimize synthesizing parameters of ZnO nanowires. The relationship between the synthesizing parameters and the desired morphology of the hierarchical structure was established. The results can be used to form various hierarchical structures to meet the requirements of different applications in nanotechnology domain, including the wettability and the adsorption of as well as the immobilization on different hierarchical structures.
