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.

双向编织碳纤维水热生长ZnO NSs及其合成参数对形貌的影响

通过水热技术在变化的工艺参数条件下开发了碳纤维编织物上的ZnO纳米结构。通过场发射枪扫描电子显微镜,能量色散谱仪(EDS)和UV-VIS-VIS分析了工艺参数(例如pH和前体溶液的摩尔浓度,生长持续时间和生长温度)对ZnO纳米结构的形态和尺寸的影响。近红外光谱。在pH> 7的情况下,获得了不同的ZnO纳米结构,如纳米托盘状,纳米花状和纳米薄片状,但在低pH条件下却获得了纳米棒状和纳米线状形态。此外,在本工作中还讨论了化学反应,晶种和生长过程对碳纤维编织物上ZnO纳米结构的影响。
