摘要

为了追求电致变色技术的进步，研究人员通过气相辅助转化和后续煅烧工艺，制备出了一种新型分层多孔镍氧化物装饰 ITO 透明导电电极。改性后的透明电极在导电聚合物薄膜的电沉积方面表现出优势，显著提高了电致变色循环的稳定性。此外，基于镍氧化物装饰的 ITO 透明电极的互补电致变色装置也已制成，并显示出快速的响应时间（着色为 1.75 秒，漂白为 0.87 秒）、高光学对比度（53.4%）和显著的循环稳定性（在 2000 次循环中光学对比度保持率为 90%）。这一发现为相关领域的应用带来了巨大潜力。

Enhanced Performance of Complementary Electrochromic Device with Hierarchical‐Porous NiO x Decorated ITO Glasses as the Transparent Conductive Electrodes

To pursuit advancing electrochromic technology, the preparation of a novel hierarchical‐porous NiOx‐decorated ITO transparent conductive electrode was developed through the vapor‐assisted conversion and subsequent calcination processes. The modified transparent electrode exhibited advantages in the electrodeposition of conductive polymer films, which significantly enhanced electrochromic cycling stability. Moreover, the complementary electrochromic device based on NiOx‐decorated ITO transparent electrode was fabricated, demonstrating rapid response time (1.75 s for coloration and 0.87 s for bleaching), high optical contrast (53.4%), and remarkable cycling stability (90% optical contrast retention over 2000 cycles). This finding holds prominent potential for applications in related fields.
