Hydrothermally grown ZnO NSs on Bi-Directional woven carbon fiber and effect of synthesis parameters on morphology

Abstract ZnO nanostructures on woven carbon fiber have been developed by hydrothermal technique under varying conditions of the process parameters. The impact of process parameters such as pH and molar concentration of precursor solution, growth duration and growth temperature on morphology and dimensions of ZnO nanostructures has been analyzed by Field Emission Gun-Scanning Electron Microscope, Energy Dispersive Spectroscopy (EDS) and UV-VIS-NIR spectroscopy. Different ZnO nanostructures of nanopallets-like, nanoflowers-like and nanoflakes-like were achieved at pH > 7 but nanorods-like and nanowires-like morphology were achieved at low pH. In addition, the impact of the chemical reactions, seeding and the growth process on ZnO nanostructures on woven carbon fibers has been discussed in the present work.
