摘要: 提出新型二维纳米材料石墨烯在航天器上的应用.首先采用超声空化法制备得到石墨烯,然后将其添加到环氧树脂中,采用共混法制成纳米复合材料.热失重分析显示材料的热稳定性能有所提高.在地面模拟设备中对环氧树脂和纳米复合材料进行了原子氧效应试验,并对试验前后材料的质量损失、表面形貌和表面成分等进行了分析,结果表明纳米复合材料相对于纯环氧树脂,其抗原子氧剥蚀性能有明显提高.Abstract: The application of graphene on spacecrafts was proposed. Graphene was prepared by the ultrasonic cavitation method, then it was added into epoxy resin and nanocomposites were prepared by the mixing method. Results of thermogravimetric analysis show that the thermal stability of the nanocomposite is improved. The atomic oxygen effect experiments of pure epoxy resin and nanocomposites are conducted in a ground-based simulation facility. Results of mass loss, surface morphology and surface composition indicate that the atomic oxygen erosion resistance of nanocomposites is improved obviously.
