Abstract: An electrochromic device has a plurality of electrochromic layers stacked sequentially with underlying electrochromic layers crosslinked. The crosslinked electrochromic layers are solution-processable without compromising their optical and electrochromic performances. The disclosed electrochromic device can produce a full-color palette with a minimized intermediate color and show a multicolor capability. Multilayer electrochromic polymer patterns with surface texture information are made. The method for controlling electrochromism or multicolor electrochromism is discussed.
