Research progress on preparation methods of VO2 nanoparticles and its application in smart windows

Abstract

Accompanied with drastic changes in photoelectric properties, vanadium dioxide (VO2) exhibits a metal-insulator phase transition (MIT) at first order with the temperature of about 68°C. These excellent thermochromic properties made VO2 an enormously potential material in the application of smart windows. VO2 nanoparticles have been extensively studying due to their unique size effect and grain boundary conditions, which can effectively reduce the temperature of metal-insulator phase transition (MIT) and hysteresis widths and improve thermochromic properties. In this paper, the preparation of VO2 nanoparticles with solution method, sputtering method, PLD deposition method and gas phase method are reviewed and also the advantages and disadvantages of various preparation methods are compared and analyzed, which considered that the solution method is the most industrial preparation method. Moreover, the recent progresses in the application of VO2 nanoparticle films on smart coatings have been reviewed, and the possible research directions of VO2 nanoparticles in the future are briefly discussed.
