THERMAL CONTROL COATINGS UNDER DEVELOPMENT AT CNES

摘要

In this paper, we have described the work conducted by CNES for protecting white pigments against the action of solar ultraviolet or ultraviolet and space particulate radiations. Treatments with oxidants have allowed us to reduce the degradation of the white paints in high proportions, especially under ultraviolet radiation alone. The qualification of these new coatings will be undertaken in the near future: thermal cycles, outgassing, surface potential, etc.. For Flexible Solar Reflectors (FSR) the first developments have allowed us to obtain polymers with good transparency and resistance to radiations fairly close to the targets sought.
