The invention discloses a vanadium dioxide (VO2) intelligent thermal control device with a longhorn beetle-imitating multistage structure and a preparation method thereof, and belongs to the technicalfield of intelligent thermal control coating layers. The problems that an existing intelligent thermal control device based on VO2 is small in emissivity change and high in solar absorption ratio aresolved. The VO2 intelligent thermal control device with the longhorn beetle-imitating multistage structure is composed of a semiconductor substrate layer, an infrared high-reflection metal layer, anHfO2 dielectric layer, a VO2 layer and a protective layer in sequence from bottom to top. The preparation method comprises the steps: 1, preparing the infrared high-reflection metal layer; 2, preparing a dielectric film; 3, preparing a VO2 film; 4, processing a microstructure; and 5, depositing a protective layer. The invention discloses the vanadium dioxide intelligent thermal control device withthe longhorn beetle-imitating multistage structure and the preparation thereof.
