摘　　要：采用同轴源型原子氧发生装置对有机硅橡胶进行地面模拟试验,经扫描电镜(SEM)、X光电子能谱(XPS)、衰减全反射傅立叶变换红外光谱(ATRFT-IR)等分析,结果表明:分子量较低的基胶制备的硅橡胶具有较好的抗原子氧辐照能力;而添加有经硅酸钾包覆处理的ZnO填料的有机硅橡胶则耐原子氧作用变差。The atomic oxygen （AO） resistance of the thermal control coatings was tested by the ground-based simulation facility of coaxial source atomic oxygen and the mechanism of AO resistance was studied by using attenuated total-internal reflection fourier transform infrared spectroscopy （ATR FT-IR）, X-ray photoelectron spectroscopy （XPS） and scanning electron microscopy （SEM）. The results show that the thermal control coatings which was made by low molecular vinyl rubber have the good resistance of AO exposure, and the filler ZnO coated by potassium silicate will make the resistance of AO exposure of the additional silicone rubber decrease.
