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.
Claims10
An electrochromic device, comprising
- a first transparent electrode;
- a plurality of electrochromic layers stacked sequentially on the first transparent electrode;
- an ion storage layer disposed on the electrochromic layers;
- and
- a second transparent electrode disposed on the ion storage layer,
- wherein:
- at least one of the plurality of electrochromic layers disposed beneath another electrochromic layer is a crosslinked electrochromic layer,
- wherein the crosslinked electrochromic layer is configured to resist solvent dissolution or swelling during solution deposition of a subsequent electrochromic layer.
