长期以来,低吸收辐射比有机温控涂层是人们着重研究的一类重要的卫星被动温控涂层,这类涂层应具有低的太阳吸收率α_s,以及高的热辐射率ε_n,即涂层必须有低α_s/ε_n值。而旦,涂层在宇宙环境中应保持该性能的长期稳定性。本文概述固外低α_s/ε_有机温控涂层的研制情况。 For a long time, low-radiation ratio organic temperature-controlled coating is one of the most important satellite passive temperature-control coatings. Such coatings should have low solar absorptance α_s and high emissivity ε_n, that is, The coating must have a low α_s / ε_n value. Once again, the coating should maintain the long-term stability of this property in a cosmic environment. This article summarizes the developments of the solid low α_s / ε_ organic temperature control coating.
