中文摘要：

VO2（M1/R）具有温度控制的可逆莫特相变性质,当材料的结晶相从VO2（M1,呈半导体状态）转变为VO2（R,呈金属状态）或者反向转变时,其光学、电学等性质发生显著变化.利用这些物理特性变化,VO2可应用于光存储、智能窗、热敏电阻和非致冷焦平面等领域.本文聚焦VO2智能窗的最新研究进展,着重介绍面向现有建筑高耗能玻璃的节能改造而研发的VO2智能节能贴膜的制备、性能、产业化和应用;综述了纳米粉体的合成、表面改性、分散和分散液的制备以及纳米印刷等技术,总结了贴膜的基本物性、耐候性和节能效果,并展望了VO2贴膜的产业化和应用前景.VO2贴膜作为我国自主研发的高科技新材料,针对我国建筑节能领域现实而迫切的应用需求,是老旧建筑玻璃节能改造的一种新材料,值得推广应用.

英文摘要：

VO2 （M1, R） demonstrates a temperature-controlled irreversible phase-transition character, which is named Mott phase transition and occurs at 68℃ for bulk VO2 （MI, R）. The Mott phase transition results in a reversible shift of VO2 between semiconductive and metallic state and is fundamental for VO2 smart window application. The smart widow can respond to environmental temperature and the temperature can be regulated in a wide range （usually 10-90℃） by a series techniques. This review focuses on the research development of VO2 flexible foils for application to the used glass. The key techniques involved in VO2 flexible foils are discussed, including the synthesis, surface modification, dispersion of VO2 nanoparticles and nano-printing, along with optical and service performance and energy efficiencies. This review also makes prospective on the further development and commercial application of the foils.
