摘　　要：本文利用磁控溅射法制备了非晶WO_(3)基无机全固态电致变色器件,并探究了其在2.5~25μm波段的发射率调制性能。实验结果显示:锂离子注入后,该器件在2.5~25μm的发射率有了明显的提升,器件整体发射率调控幅度为0.3。基于Thermal desktop软件,对非晶WO_(3)基电致变色器件的航天器热控能力进行了仿真。热仿真结果表明:非晶WO_(3)基无机全固态电致变色器件能大幅度降低热控功耗,表现出较好的热控性能。An all-solid-state electrochromic device composed of amorphous WO_(3)as the electrochromic layer has been prepared using magnetron sputtering,and the infrared emittances of the devices is studied in detail.The experimental results show that the emissivity of the device in the spectral range of 2.5‒25μm increase greatly after lithium-ion insertion,and its emissivity modulation is about 0.3 in the spectral range of 2.5‒25μm,which shows a potential on thermal control of satellites.Several simulation experiments were carried out in Thermal desktop(TD)software,and the results of simulation proposed the thermal control capacity of the electrochromic devices based on amorphous WO_(3).The results of simulation experiments showed that the electrochromic intelligent thermal control technology can meet the requirements of spacecraft thermal control in different on-orbit conditions and greatly reduce the thermal control power consumption.
