Abstract
In order to develop a smart variable emittance thermal control coating, we here report on a flexible solid-state electrochromic device(ECD) based on soluble polyaniline by simple fabrication process. Devices were as- sembled in sandwich configuration of electrochromic materials on flexible PET substrate and a Li~ doped polyacryloni- trile as a solid polymer electrolyte. The initial surface emissivity characteristics related to oxidation states, doping con- centration, doping agent and thickness were discussed. The smart thermal management of this ECD was characterized by its emittance in view of the thickness of active layer and the applied voltage. The emittance of our ECD can be tuned from 0.46 to 0.75 without any fine optimization, which is similar to that of other solid-state ECDs. The major advantage of this work is that the electrochromic variable emittance coating can be preparedby using simple process, such as spin coating and spray coatings. These methods do not require any special equipments and vacuum working conditions, and are easily applied for large area process as well. This study may open new avenues in the development of flexible electrochromic devices for spacecraft thermal control.关键词
