Stable and multicolored electrochromic device based on polyaniline-tungsten oxide hybrid thin film

In this study, tungsten oxide (WO3) film was used to enhance the stability as well as the performance of electrochromic window (ECW) based on famous conductive polymer-polyaniline (PANI). PANI and WO3 films were prepared and employed to fabricate hybrid ECW with an unprecedented stability (over 1000 cycles) and more colorful device with various color (green, blue, and violet of neat PANI, and deep blue of WO3). The multicolor nature of device...
