Photo-thermal dual-response intelligent window and preparation method thereof

The invention discloses a photo-thermal dual-response intelligent window and a preparation method thereof. The intelligent window comprises a gel layer, wherein the gel layer comprises hydrogel formed by temperature-sensitive amide monomers and polydopamine modified nanocellulose, and the mass percentage of polydopamine to the temperature-sensitive amide monomers is 0.001%-0.02%. According to the intelligent window, amide hydrogel with a temperature-sensitive property is adopted as a substrate, then a polydopamine modified nanocellulose material with a photo-thermal conversion function is added, and the intelligent window with photo-thermal double response is prepared. When the light intensity is large or the room temperature is high, the intelligent window automatically changes from transparent to opaque, natural light is scattered, indoor light is not dazzling but still bright, and meanwhile, the indoor temperature can be kept at the human body comfort level. When the light intensity is reduced and the temp
