| Abstract: |
| The significant changes in the surface morphology of polymer films used in spacecrafts due to the action of atomic oxygen (AO) in orbit degrade the service performance of spacecrafts. In this paper, relevant researches were reviewed from the aspects of experiment and simulation. The changes of roughness and transmittance of polyimide films under AO exposure were reviewed. It was found that with the increase of AO fluences, the roughness was increased, the transmittance was decreased, but the rule of change was still unclear. Then modification of polyimide films, other polymer films and morphological changes of polymer films under synergistic effects of space environments were reviewed and analyzed. Then simulation methods of AO with polymer were analyzed, and the published simulation results of AO undercutting were summarized, and key scientific problems in the study of the morphology change mechanism of polymer films were pointed out. |
