摘要：
Black polyimide film is electrically conductive with high solar absorptance and high infrared emittance. The material can be applied as satellite thermal control film to enhance radiative heat transfer and thereby help isothermalize the components of spacecraft. The film can be used in satellite optical devices and telescopes baffle systems to minimize reflection from stray light. In this paper the degradation of solar absorptance of black polyimide film under simulated space environment tests such as thermal cycling, ultraviolet irradiation, proton irradiation and electron irradiation are reported. The test results show that the black polyimide film has very good stability in simulated space environment.
