Evaluation of two new white silicone thermal control paints under atomic oxygen

Preparation and characterization of diphenyl silicone rubber/microfiber glass wool composite thermal control films

“…Therefore, the infrared emittance, ε of the second surface mirror depends on the thickness of the surface thin film. 8–10…”

“…Therefore, the infrared emittance, 3 of the second surface mirror depends on the thickness of the surface thin lm. [8][9][10] The currently used SSM coatings are mainly polyimide/Al and uoropolymer/Ag. Both polyimide and uoropolymer are high temperature resistant resins with high infrared emittance 3 and good light transmittance.…”

Ladder Polyphenylsilsesquioxanes and Their Niobium–Siloxane Composite as Coating Materials: Spectroscopy and Atomic Oxygen Resistance Study

“…The traditional approach through the addition of fillers and modifiers makes it possible to partially solve this problem [ 16 , 17 , 18 , 19 , 20 ] that, in fact, prevents silicones from competing, for example, with polyimides capable of withstanding AO flow. Currently, silicones, due to their ability to form an inorganic protective layer when exposed to AO, play the role of a “second component” for polyimides.…”

Study of resistance performance of Al2O3–ZnO–Y2O3thermal control coating exposed to vacuum-ultraviolet irradiation

“…6 In particular, inorganic thermal control coatings have a low radiation-absorption ratio and excellent stability in the space environment, which is preferred for spacecra cooling surface at present. 7,8 Because the thermal control coating is located on the outer surface of the spacecra, it will be directly exposed to the harsh space environments, such as high vacuum, charged particles, ultraviolet radiation, atomic oxygen and so on. [9][10][11][12] Among the harsh space environments, it is worth noting that the vacuum-ultraviolet radiation will cause the serious degradation of thermal control performance and affect its function because high-energy UV photons can cause "color center" generation on the inorganic thermal control coating surface.…”
