Research Progress on Functional Design and Application of Electrochromic Materials
Electrochromic materials have important application prospects in energy-saving windows,smart displays,and military camouflage protection,as they can stably and reversibly change their optical properties under an external electric field.By multi-component synergistic methods,electrochromic devices can integrate more functions or new features,making them develop towards the direction of multifunctional integration and further expanding their application fields.In this article,we comprehensively reviewed the latest research results on the functional design of electrochromic devices in the past decade and discussed their integration mode,working mechanism,and design strategies.We elucidated their application prospects in smart windows,energy storage devices,sensors,and military camouflage,and analyzed in detail the key problems and major challenges of functional electrochromic devices.We also proposed new solutions and development directions,which are of great significance for guiding the research on the functionalization of electrochromic devices.
