  Abstract

Electrochromism is a phenomenon in which materials change color reversibly through electrochemical oxidation and reduction reactions when an external voltage is applied. Viologens are commonly used as organic electrochromic materials in all-in-one ion gel compositions due to their electron-accepting ability and versatile synthesis routes. However, their integration into polymers for ion gel preparation is not well-reported. With growing interest in wearable devices, significant efforts have been made to develop advanced electrochromic materials for flexible electrochromic devices (ECDs). In this study, we synthesized a viologen-incorporated stretchable polymer and applied it to ECD fabrication on an ITO-PET substrate. The prepared flexible ECDs operated at a voltage of -2.5 V, exhibiting a high optical contrast of 83.9% at 600 nm, a coloration efficiency of 82.8 cm²/C, long-term switching stability up to 9000 s, and switching times under 20 s. Additionally, these viologen-incorporated polymer ECDs demonstrate durability when bent, proving their suitability for upcoming technologies like smart displays and wearable gadgets.
