摘要
电致变色材料是一类在外加电场作用下可逆改变光学属性的智能材料,广泛应用于智能调光玻璃、显示器、储能器件等领域。氧化钨作为电致变色材料的典型代表,因其具有高光学调制率、良好的循环稳定性等优点而备受关注,但传统氧化钨电致变色器件色彩调制单一,难以满足多彩显示和美学需求。近年来,基于结构色的多彩电致变色研究取得重要进展,为氧化钨色彩调控提供了新思路。本文梳理了基于颜色混合与光学谐振腔策略的氧化钨多彩电致变色材料与器件的研究进展,重点分析其色彩调控机制与性能优化方法。通过构建谐振腔结构,氧化钨电致变色电极实现了丰富色彩的动态调制,展现出在显示、智能伪装与可视化储能等领域的应用潜力。最后,本文总结了当前技术挑战并展望了未来发展方向,旨在为相关研究提供理论支持与技术参考。
Electrochromic materials are a class of smart materials that reversibly change their optical properties under an applied electric field and are widely used in smart windows,displays,energy storage devices,and other fields.Tungsten oxide,as a typical representative of electrochromic materials,has attracted significant attention due to its high optical modulation and good cycling stability.However,traditional tungsten oxide electrochromic devices offer only single-color modulation,making it difficult to meet the requirements for multicolor displays and aesthetic demands.In recent years,significant progress has been made in research on multicolor electrochromism based on structural color,providing new ideas for color modulation of tungsten oxide.This paper reviews the research progress in tungsten oxide-based multicolor electrochromic materials and devices based on color mixing and optical microcavity strategies,focusing on analyzing their color modulation mechanisms and performance optimization methods.By constructing microcavity structures,tungsten oxide electrochromic electrodes have achieved dynamic modulation of rich colors,demonstrating application potential in displays,smart camouflage,and visualizable energy storage.Finally,the paper summarizes current technical challenges and prospects future development directions,aiming to provide theoretical support and technical references for related research.
