Research aimed at developing a wearable electrochromic fabric providing active camouflage has been ongoing for many years. Despite recent progress, no architecture has been shown to be suitable for practical applications, due to some major problems at the device level. The complicated structure of these prototype devices and their complex electrode materials reduce their practicability and make it difficult to achieve the aim of chameleon-like camouflage capabilities. Here, we use a laterally-configured electrode structure and inexpensive and commercially available ITO film as electrodes to construct an electrochromic (EC) fabric via an all-solution process. This novel EC fabric exhibits camouflage EC performance by changing colour between vegetable-green and soil-brown; it is also practical for camouflage applications due to its excellent flexibility and stability as well as being thin and lightweight. Moreover, this strategy can also be used to fabricate flexible transparent EC devices on plastics and “chameleon camouflage” on human skin. This approach is simple to configure and easy to operate, and has potential for the development of EC device systems that can change colour in camouflage applications.

多年来致力于开发可提供主动伪装的可穿戴电致变色织物的研究一直在进行。尽管有最新进展，但由于设备级的一些重大问题，尚未显示出适合于实际应用的体系结构。这些原型设备的复杂结构及其复杂的电极材料降低了其实用性，并使其难以达到变色龙般的伪装能力的目的。在这里，我们使用横向配置的电极结构和便宜且可商购的ITO膜作为电极，以通过全溶液工艺构造电致变色（EC）织物。这种新颖的EC织物通过在蔬菜绿色和土壤棕色之间改变颜色而表现出迷彩EC性能。由于其出色的柔韧性和稳定性以及超薄和轻巧的特性，它在伪装应用中也很实用。此外，该策略还可用于在塑料上制造柔性透明EC器件，并在人体皮肤上制造“变色龙伪装”。这种方法易于配置且易于操作，并且具有开发可在伪装应用中改变颜色的EC设备系统的潜力。
