英文摘要：

In terms of potential applications in electrochromie devices such as military disguise, car mirrors, high contrast displays, as well as smart windows of buildings, polyoxometalates are promising candidates due to their diverse structures and good reversible redox activities. The recent progress in the research of electrochromic materials containing polyoxometalates is reviewed. This paper introduces the electrochromic mechanism of the polyoxometalates and the preparation methods of thin films of polyoxometalates, including sol-gel, electrodeposition, Langmuir-Blodgett and layer- by-layer self-assembly method. It gives priorities to research situation and progress in electrochromism of isopoly-acid and heteropoly-acid electrochromic materials. Furthermore, the major classes of polyoxometalate electrochromic materials are described in detail. Finally, the research orientation and development tendency about electrochromic materials based on polyoxometalates are forecasted.
