Recent progress and advances in electrochromic devices exhibiting infrared modulation

Abstract

Infrared electrochromic devices (IR-ECDs) that dynamically regulate the IR optical properties of the objects have gained increasing attention in a wide range of applications such as controllable thermal management and adaptive military camouflage. In this review, detailed summaries and discussions of the recent advances and progress in IR-ECDs are presented. We demonstrate the fundamentals of IR-ECDs, including the working principle, special device configuration as distinguished from the conventional ECDs, and the main performance parameters of the device. The latest research progress on the construction and applications of IR-ECDs is summarized in detail according to the classification of inorganic EC transition metal oxides and organic EC conducting polymers. Some prospects and challenges for the further development of the IR-ECDs are also proposed. This review is anticipated to provide guidance for constructing advanced IR-ECDs towards real world applications in both civilian and military.
