Wearable e-textile displays have shown great potential for displays, decoration and sensors. In this regard, electrochromism has collected broad interest for color-changing behaviors, as it exhibits reversible color changes by an electrochemical redox reaction. Viologens find advantages due to low-voltage operation and ion-gel preparation for electrochromic devices (ECDs). When incorporated in ion gel composition, the ECDs show much enhanced electrochromic behaviors. Herein we present the preparation and electronic properties of electrospun nanofiber-based ECDs. Fiber-type ECDs are fabricated using Ag and Ni electrodes, with electrospun nanofibers as an active layer. The reversible and repeated color-switchings from colorless to distinctive blue are manifested. The electrochromic and structural properties are investigated by cyclic voltammetry, kinetic stability, and SEM measurements. In doing so, we intend to prove the feasibility of fiber-type ECDs for wearable e-textile displays. |
