Abstract The latest progress in research,development,and application of the flexible thermal control thin filmmaterials in space industry was tentatively discussed in a thought provoking way.The discussions centered on the working principles and wide applications of the flexible thermal control films in fabrication of a variety of devices widely used in spacecraft,such as the firs-t surface mirrors,second-surface mirrors,thermal control tapes,and corrosion-resistant coatings.The performance ofthe typical productsmade ofthe flexible thermal control films,imported andmade in China,were compared. The development trends and favorite properties of some advanced, intelligent,thermal control films materials,including the phase-change films and the polyimide silver-based composite membrane(CCAG)membranes were also briefly discussed.
Keywords Flexible,Thermal control,Film,Second-surface mirrors,Spacecraft
