A light-weight, thin-thickness, flexible multifunctional electrochromic device integrated with variable optical, thermal management and energy storage
Multifunctional electrochromic devices with diversified functions are highly desirable for intelligent electronic systems compared to conventional electrochromic devices with sole applicability. Herein, a multifunctional electrochromic device integrated with variable optical, thermal management and energy storage is realized by preparing nanowire‐structured coral-like PANI films on a flexible gold-plated membrane through the combination of galvanostatic and cyclic voltammetric electrodeposition techniques. The multifunctional electrochromic devices achieve reversible color changes between brownish-yellow, green and dark-green. The maximum emissivity changes of the multifunctional electrochromic device in the ranges of 3–5 μm, 8–14 μm and 2.5–15 μm are 0.42, 0.49 and 0.47, respectively. Moreover, a specific capacitance of 355 F g −1 is obtained for the multifunctional electrochromic devices at a current density of 1 A g −1 . The multifunctional electrochromic devices also have such advantages as light-weight, thin-thickness, flexible and can be fabricated in a multipixel and large area. With versatility characteristics, the multifunctional electrochromic devices are highly promising for intelligent electronic systems in electronic clothing, military camouflage and thermal control system of spacesuits.
