Abstract

Dynamic thermal management is useful for maintaining personal thermal comfort. However, integrating multifunctionalities into flexible thermal management device remains challenging. Inspired by color modulation mechanisms of cephalopod skin, we demonstrate a flexible electro-driven nanophotonic (FEN) device with dual-functionalities of dynamic radiative thermoregulation and all-time energy supply. Flexibility is achieved by depositing nanoscaled silicon film onto a flexible nanoporous separator. High IR emissivity regulation from 0.85 (cooling mode) to 0.19 (heating mode) at 8–13 μm is achieved, accompanied by an apparent temperature modulation of 13 °C. Besides, integrated energy storage performance shows a superior areal capacity of ∼0.35 mAh cm^–2 and a Coulombic efficiency of ∼70%. Additionally, we propose a tunable mechanism of electro-optical-thermal conversion via the reversible insertion/extraction of lithium ions in silicon film. We believe that such flexibility and multifunctionality will position our FEN device as a versatile platform for next-generation personal thermal management, energy storage systems, and information encryption technologies.

用于动态辐射温度调节和能量储存的柔性电驱动纳米光子器件。

动态热管理对保持个人热舒适是有用的。然而，将多功能集成到柔性热管理设备中仍然具有挑战性。受头足类动物皮肤颜色调制机制的启发，我们展示了一种柔性电驱动纳米光子（FEN）装置，具有动态辐射温度调节和全天候能量供应的双重功能。柔性是通过在柔性纳米孔分离器上沉积纳米级硅膜来实现的。在8-13 μm范围内实现了从0.85（冷却模式）到0.19（加热模式）的高红外发射率调节，并伴有13°C的表观温度调制。此外，集成储能性能显示出优越的面容量（~ 0.35 mAh cm-2）和库仑效率（~ 70%）。此外，我们提出了一种可调的电光热转换机制，通过可逆的锂离子在硅膜中的插入/提取。我们相信，这种灵活性和多功能性将使我们的FEN设备成为下一代个人热管理、能量存储系统和信息加密技术的通用平台。
