Experimental investigations of the respective and synergistic effects of vacuum ultraviolet radiation and atomic oxygen on a spacecraft material——Kapton

  • Kapton is a commonly used spacecraft material, on which the experiments are constructed to investigate the VUV (vacuum ultraviolet radiation) effects and its synergistic effects with AO (atomic oxygen) in a ground-based simulation facility. The sample materials before and after the tests are compared in appearance, mass loss, surface morphology, optical properties and surface composition. Through the analysis of the reaction mechanism between VUV, AO and Kapton, it was concluded that the oxidation of the carbon and nitrogen is the main reason of the erosion of Kapton. Because the sample surface will be cross-linking and form large molecule under VUV radiation, the AO-resistance characteristic of thesample is improved. But with the increasing of AO fluence, the effect disappears gradually, and the VUV cannot affect the results of the AO exposure experiment.
