Abstract

Due to its unique phase transition properties, vanadium dioxide (VO₂) has attracted significant attention in smart window applications. However, VO₂ currently has some shortcomings in the phase transition field, mainly including the uncontrollability of the phase transition process, insufficient crystallinity, and weak bond strength. Therefore, this study prepared M-phase VO₂ with high crystallinity through annealing treatment, significantly enhancing the bond strength between vanadium and oxygen atoms, thus improving the material's stability. This enhanced stability reduces energy barriers during the phase transition, making the transition more controllable and reversible. The prepared VO₂(M) exhibits a distinct endothermic peak at 67.40°C, with a peak heat flow of 0.59W/g. The results indicate that M-phase VO₂ prepared through simple annealing treatment is highly suitable for applications requiring efficient phase change materials, overcoming the shortcomings of traditional VO₂ materials in the phase transition field.
