Reflectance and Emittance of Selected Materials and Coatings
Abstract
A literature review was made to provide the reflective and thermal radiative properties (emittance) of a number of selected materials and surface coatings applicable to a few specific satellites. With the data provided, the infrared radiation signature for each surface may be evaluated from both a spectral and directional basis. Properties defined include solar absorptance, normal and hemispherical emittance, spectral reflectance and emittance, and directional (angular) reflectance and emittance. Pertinent data which aid in predicting degradation of the solar absorptance in the space environment are also presented. The selected materials include aluminum alloy 6061, titanium alloy 6Al-4V, beryllium, various titanium dioxide and zinc oxide pigmented (white) coatings, solar cells, optical solar reflectors (second surface mirrors) , using both rigid and flexible substrates, black pigmented coatings, and clear and black anodized aluminum coatings.
