Research progress of infrared electrochromic devices

Abstract

Infrared electrochromic device is a kind of device whose infrared emissivity can change reversibly under electric field excitation. This kind of device has important applications in the fields of adaptive infrared camouflage and intelligent thermal control, and has become a research frontier and hot spot in the field of infrared radiation control. In this paper, the working principle, research status and progress of infrared electrochromic devices based on metal oxides, conductive polymers, graphene and metals are summarized, and the development trend of infrared electrochromic device is analyzed.
