Abstract
It is well-known that tungsten oxide (WO3) is extensively used for electrochromic (EC) devices due to their special properties such as high coloration/bleaching response time, good coloration efficiency and so on. The preparation of flexible EC devices is highly desirable for various applications. However, the fabrication of flexible EC devices with improved performance is still major task due to their limited experimental protocols. In this work, we have prepared thr highly flexible transparent films consisting of WO3 and silver nanowires coated on nanofiber-reinforced composite films (WO3/AgNWs-NCF). The novel flexible transparent WO3/AgNWs-NCF is used for the electrochromic (EC) applications. The as-fabricated EC device based on WO3/AgNWs-NCF demonstrated a good coloration efficiency (161.3 cm2/C), excellent stability (81.5 %), and rapid respone time for coloration (2.9 sec) and bleaching (3.2 sec). The fabricated transparent flexible EC device may be potentially useful to design an outstanding EC device for a smart window application.
