摘要
利用空间原子氧地面模拟试验研究了碳纳米管阵列的原子氧剥蚀效应。用扫描电子显微镜观察碳纳米管阵列经不同注量原子氧辐照后的形貌,并测量了剥蚀长度。结果表明,碳纳米管阵列在原子氧作用下发生剥蚀效应,原子氧注量不同则剥蚀率有一定的差异,其形貌也有明显的变化。原子氧的轰击和氧化是碳纳米管阵列发生原子氧剥蚀的原因。基于这些结果提出了原子氧剥蚀碳纳米管阵列过程模型。
The atomic oxygen（AO） irradiation induced erosion of carbon nanotube（CNT） arrays has been investigated by ground-based atomic oxygen simulation facility. The heights and the surface morphologies of CNT arrays before and after AO irradiation have been characterized by scanning electron microscope（SEM）. The results show that CNT arrays can be etched away in AO environment, but the erosion rate of CNT arrays varied with the radiation flux of AO. The morphologies of CNT arrays are also quite different from those before AO irradiation. The erosion of CNT arrays can be attributed to the bombardment effect and the oxidation effect of AO. Finally, a model for describing the process of AO erosion of CNT arrays is proposed.
