The invention discloses a near-infrared shielding thermochromic intelligent window and a preparation method thereof, and belongs to the field of radiation refrigeration and intelligent windows. The problems that an existing thermochromic intelligent window is high in near infrared transmittance and low in middle and far infrared heat radiation regulation and control amplitude are solved. A near-infrared shielding thermochromic intelligent window is composed of a substrate, a hyperbolic metamaterial structure, a first oxide dielectric layer and a VO2 metasurface layer in sequence from bottom to top. The preparation method comprises the following steps: 1, cleaning the substrate; 2, preparing a hyperbolic metamaterial structure; 3, preparing a first oxide dielectric layer; and 4, preparing the VO2 metasurface layer. The thermochromic intelligent window for near-infrared shielding and the preparation method thereof are provided.

    一种近红外屏蔽的热致变色智能窗及其制备方法,它属于辐射制冷、智能窗领域。本发明要解决现有热致变色智能窗近红外透过率高、中远红外热辐射调控幅度低的问题。一种近红外屏蔽的热致变色智能窗,它自下而上依次由基底、双曲超材料结构、第一氧化物介质层及VO2超表面层组成。制备方法:一、清洗基片;二、双曲超材料结构的制备;三、第一氧化物介质层的制备;四、VO2超表面层的制备。本发明用于近红外屏蔽的热致变色智能窗及其制备。
