Abstract:

Thin-film multilayer electrochromic coatings for thermal control of spacecraft were designed, built and tested. Design was for a 300 degrees K spacecraft. but coatings would also work well for warmer surface emittance control. Changes in emissivity of dE0.2, and ratios of on to off emissivity were as high as 3.5. Further work is needed to improve reproducibility of results and long-term stability.
