Angle-independent VO₂ Thin Film on Glass Fiber Cloth as a Soft-Smart-Mirror (SSM).

ABSTRACT: Designing materials with a negative feedback function is beneficial for achieving temperature regulation inside a greenhouse. VO₂ has been studied extensively because of its low insulator-to-metal transition temperature (IMT). In this study, reflection changes during a VO₂ phase transition were investigated. Glass fiber cloth was used as a substrate, as it is stable and soft. A VO₂ thin film on a glass fiber cloth whose surface contained 96% V⁴⁺ and 4% V⁵⁺ was prepared using an inorganic sol-gels method. The insulator-to-metal transition temperature was decreased by 38 °C, which was observed from the reflection curve detected using an angle-resolved spectrometer. This decrease in IMT occurred mainly because of the presence of V^5+<
