摘要

基于可逆金属电沉积（RME）的智能窗户可实现较大的太阳辐射热获得系数（SHGC）调节，其中Zn-RME是一种具有高理论着色效率（CE）、成本效益和色彩中性的有趣选择。本文选择 Cu2+ 作为电解质添加剂，以降低金属电镀过程中的活化能并均匀电场分布，通过可逆合金电沉积（RAE）形成梯度 CuZn 合金纳米颗粒。与 Zn-RME 相比，CuZn-RAE 电极可在 2 分钟内实现极低的透射率（0.01%）和中性色（色度 C* = 5.8）、较大的透射率调制（82%）、快速切换时间（tc = 8 秒，tb = 18 秒）、更高的 CE 值、更高的记忆效应以及更长的循环稳定性。此外，着色的 CuZn-RAE 器件能有效阻挡红外热，使表面温度降低 7.1 °C，使用 CuZn-RAE 器件建模的中空玻璃单元（IGU）具有较大的太阳热调节能力，ΔSHGC 为 0.448，显示出动态智能窗的巨大应用潜力。

Color-Neutral Smart Window Enabled by Gradient Reversible Alloy Deposition

Reversible metal electrodeposition (RME)-based smart windows can realize large solar heat gain coefficient (SHGC) modulation, where Zn-RME emerges as an intriguing option with high theoretical coloration efficiency (CE), cost effectiveness, and color neutrality. Herein, Cu²⁺ was selected as electrolyte additive to lower the activation energy and homogenize the electrical field distribution during metal plating, forming gradient CuZn alloy nanoparticles via reversible alloy electrodeposition (RAE). Compared to Zn-RME, the CuZn-RAE electrode can achieve extremely low transmittance (0.01%) and color neutrality (chroma C* = 5.8) within 2 min, large transmittance modulation (82%), fast switching times (t_c = 8 s, t_b = 18 s), higher CE, elevated memory effect, and extended cycling stability. Additionally, a tinted CuZn-RAE device can effectively block infrared heat and reduce surface temperature by 7.1 °C, and the insulating glass unit (IGU) modeled with a CuZn-RAE device offers large solar heat modulation with ΔSHGC of 0.448, showing great application potential toward dynamic smart windows.
