Abstract:

Prussian blue (PB) and its analogues, as classic inorganic electrochromic materials, have shown great application potential in fields such as smart Windows, automotive sunroofs and low-power displays due to their advantages of low cost, high coloration efficiency and neutral color. This work systematically reviews the multicolor electrochromic mechanism of PB-based analogues, elucidates the role of water molecules in the electron-transfer process, and summarizes the characteristics and applicability of common preparation methods. On this basis, it focuses on outlining the electrochromic properties of PB-based composites and their applications in smart Windows, automotive sunroofs, and display fields. It further discusses the key challenges and future development trends facing PB-based electrochromic materials in practical applications. Overall, this review provides theoretical references and technical support for the performance optimization and application expansion of PB-based analogues, while outlining future directions and potential breakthroughs in the field of intelligent optoelectronics.
