A simple and low-cost combustion method to prepare monoclinic VO2 with superior thermochromic properties

In this approach, the VO 2 nanoparticles have been successfully fabricated via combusting the low-cost precursor solution consisted of NH 4 VO 3 , C 2 H 6 O 2 and C 2 H 5 OH. By the XRD, TEM and XPS analysis, it can be found that the synthetic monoclinic VO 2 is single crystal and no impurity is def...

Summary:In this approach, the VO 2 nanoparticles have been successfully fabricated via combusting the low-cost precursor solution consisted of NH 4 VO 3 , C 2 H 6 O 2 and C 2 H 5 OH. By the XRD, TEM and XPS analysis, it can be found that the synthetic monoclinic VO 2 is single crystal and no impurity is defined. After dispersing the VO 2 nanoparticles into the polymer, the solar modulation of VO 2 -based composite film is up to 12.5% with luminous transmission and haze around 62.2% and 0.5%, respectively. In other words, the composite films show high performance of thermochromic properties. This could open an efficient way to fabricate low-cost and large-scale VO 2 (M) nanoparticles and thermochromic films.
