正在开发响应性纳米材料，以创建新的独特功能，例如可切换的颜色和粘合剂特性或响应外部刺激的其他可编程功能。虽然许多现有的例子依赖于温度，湿度或pH值的变化，但本研究旨在探索一种依赖于简单电输入信号的替代方法。更具体地，使用碳纳米管-锡（Sn）复合材料开发3D电致变色架构的微结构，所述碳纳米管-锡复合材料可以通过以低功率电输入（150千瓦）锂化Sn来重新配置。这些微结构具有由电化学锂化过程的程度决定的连续、可调节且非挥发性的致动。此外，这种拟议的制造工艺仅依赖于批量光刻技术，能够并行生产数千个3D微结构。证明了在致动时开口端面积变化30-97%的结构，并强调了电化学致动期间3D架构微结构的响应和结构完整性中几何因素的重要性。
Responsive nanomaterials are being developed to create new unique functionalities such as switchable colors and adhesive properties or other programmable features in response to external stimuli. While many existing examples rely on changes in temperature, humidity, or pH, this study aims to explore an alternative approach relying on simple electric input signals. More specifically, 3D electrochromic architected microstructures are developed using carbon nanotube–Tin (Sn) composites that can be reconfigured by lithiating Sn with low power electric input (≈50 nanowatts). These microstructures have a continuous, regulated, and non‐volatile actuation determined by the extent of the electrochemical lithiation process. In addition, this proposed fabrication process relies only on batch lithographic techniques, enabling the parallel production of thousands of 3D microstructures. Structures with a 30–97% change in open‐end area upon actuation are demonstrated and the importance of geometric factors in the response and structural integrity of 3D architected microstructures during electrochemical actuation is highlighted.
