Thermal control coatings is a kind of passive thermal control technology used in spacecraft thermal design. The appropriate thermal control coating can be used to keep certain parts of the spacecraft in the desired temperature range, which plays an important role in the normal operation of spacecraft. This paper first introduces the concept and basic principle of thermal control coatings. Thermal control coatings are classified according to their thermal radiation properties and composition. Various kinds of thermal control coatings are described in detail according to different preparation methods. The main differences of coating-type thermal control coatings at home and abroad are analyzed. Then the properties of various thermal control coatings are compared from the aspects of thermal radiation properties, space stability, substrate applicability, adhesion, cleaning and process. At the end of the paper, the shortcomings of thermal control coatings for spacecraft in china are pointed out, and the future development direction of thermal control coating technology for spacecraft is prospected.
