The 16th International Meeting on Electrochromism (IME-16) (IME-16)

Electrochromism refers to the phenomenon whereby the optical properties of a material undergo reversible changes through external electric field actuation. This paper focuses on zinc anode-based electrochromic device (ZECD) and presents three studies aimed at achieving multicolor and broad-spectrum control. The first study utilized phytic acid-doped PANI to develop a multicolor (transparent, yellow, blue, deep purple) ZECD with four operating modes: bright, cool, dark and warm. The second study coupled the reversible Zn electrodeposition with ion-inserted PB to design the ZECD with neutral color. The third study developed a Zn/MnO₂ dual-electrodeposition-based ZECD with a wide light modulation range and neutral color, further simplifying the device structure. The above findings offer new insights for the development of next-generation high-performance electrochromic smart windows.
