In this approach, the VO nanoparticles have been successfully fabricated via combusting the low-cost precursor solution consisted of NHVO, CHO and CHOH. By the XRD, TEM and XPS analysis, it can be found that the synthetic monoclinic VO is single crystal and no impurity is defined. After dispersing the VO nanoparticles into the polymer, the solar modulation of VO-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 (M) nanoparticles and thermochromic films.
在此方法中，通过燃烧由 NHVO、CHO 和 CHOH 组成的低成本前体溶液，成功制备了 VO 纳米颗粒。通过 XRD、TEM 和 XPS 分析，可以发现合成的单斜 VO 是单晶，没有定义杂质。将 VO 纳米颗粒分散到聚合物中后，基于 VO 的复合膜的太阳能调制达到 12.5%，光透射率和雾度分别约为 62.2%和 0.5%。换句话说，复合膜表现出优异的热致变色性能。这为制备低成本、大规模的 VO（M）纳米颗粒和热致变色薄膜开辟了一条有效途径。
