内容記述 | In Low Earth orbit (LEO) where 200-500 km in altitude, highly reactive atomic oxygen, which is the dominant species in the upper atmosphere of the Earth, bombards the polyimide surface which is widely used as a passive thermal control material at the exterior of spacecraft. Erosion of polyimide by atomic oxygen is very severe, research efforts have been intensively paid in the last two decades. Since polyimide has also been widely used in electrical systems of satellites, this paper provides an overview of the erosion properties of polyimide materials in an LEO space environment through ground-based simulation. The ground-based simulation technique and recent research results regarding hyperthermal atomic oxygen reaction with polyimide are described, including changes in surface composition due to air exposure, non-linear mass loss phenomenon, impingement angle and sample temperature dependences on gasification reaction. The synergistic effect on polyimide erosion with ultraviolet exposure in LEO and surface charging are also discussed. | |||||
