Electrochromic (EC) technology, with its reversible color changes and special light modulation, has a wide range of applications in adaptive military camouflage. However, there are still some problems such as difficulties with multicolor display, flexible patterned displays, and difficult integration with electrochromic and energy storage that limit its development and applications in portable military camouflage devices. In this work, a multicolored conjugated polymer, p3DT-FSQ, was designed and prepared by electrochemical polymerization. The polymer film exhibits a reversible color change, high optical contrast, and a fast switching time. On this basis, the reflective and transmissive zinc-based electrochromic devices (RZECD and TZECD) were optimally assembled based on the p3DT-FSQ film as the EC layer and zinc sheet or zinc frame as the counter electrode. Both RZECD and TZECD show reversible orange-yellow, earthy yellow, and army green colors at various potentials with good energy storage properties and excellent flexibility, meeting the demand for color variation and functionality in modern electronic combat environments. It is even more intriguing that the patterned TZECDs can accurately simulate six combat environments, including Gobi, highland, wilderness, cropland, desert, and forest. This work presents a design strategy for an adaptive EC military camouflage device that also has an energy storage function, making it an excellent choice for portable adaptive military camouflage.

用于自适应军事伪装的柔性全固态锌基电致变色储能装置


电致变色 （EC） 技术具有可逆的颜色变化和特殊的光调制，在自适应军事伪装中具有广泛的应用。然而，仍然存在一些问题，如多色显示困难、柔性图案显示以及难以与电致变色和储能集成，限制了其在便携式军用伪装装置中的开发和应用。在这项工作中，通过电化学聚合设计并制备了一种多色共轭聚合物 p3DT-FSQ。聚合物薄膜具有可逆的颜色变化、高光学对比度和快速切换时间。在此基础上，以 p3DT-FSQ 薄膜为 EC 层，锌片或锌框架为对电极，优化组装了反射和透射锌基电致变色器件（RZECD 和 TZECD）。RZECD 和 TZECD 均表现出各种电位的可逆橙黄色、土黄色和军绿色，具有良好的储能性能和出色的柔韧性，满足现代电子作战环境中对颜色变化和功能的需求。更有趣的是，图案化的 TZECD 可以准确模拟六种战斗环境，包括戈壁、高原、荒野、农田、沙漠和森林。这项工作提出了一种自适应 EC 军用伪装装置的设计策略，该装置还具有储能功能，使其成为便携式自适应军用伪装的绝佳选择。
