Perovskite structure manganese oxide thermal control coatings were synthesized by solid-state reac-tion method.The relationship between the total hemispherical emittance (εH )and the temperature of the ther-mal control coatings was measured on a calorimetric emissometer which was based on the steady state calorime-tric method.The compounds show thermochromic properties andεH have low value at low temperature and have high value at high temperature.Environmental adaptability tests such as ultraviolet irradiation test,pro-ton irradiation test,electron irradiation test,thermal cycle test,outgassing test were conducted also.The test results showed that thermal control coatings had very good space stability performance,which made the ther-mal control coatings attractive as potential active thermal control materials for future satellites.
