The erosion effects of atomic oxygen (AO) in different incidence direction on carbon nanotube (CNT) arrays have been studied by ground‐based AO simulation facility. The surface morphologies and the molecular structures of CNT arrays before and after AO experiments have been characterized by scanning electron microscopy and Raman spectroscopy. It is shown that the morphologies of CNT arrays are quite different from those before AO experiments. It is presented that both bombardment effect and the oxidation effect of AO will contribute to the erosion effects on CNT arrays. Carbon nanotube arrays will be etched away in AO environment, but the AO erosion yield of CNT arrays is different with different AO incidence direction. It is proposed that the density of CNT‐based material may also affect the erosion yield.
