today’s cyclodextrin is something smart and unique – heat-responsive, intelligent window. In practice, temperature-sensitive cyclodextrin as a solute and water and glycerol as solvents are injected into an interlayer of a double-layer window panel to obtain the thermal response liquid intelligent window. The thermal response liquid intelligent window is prepared from safe, non-toxic and environment-friendly raw materials through a simple and feasible preparation method in accordance with the green and environment-friendly concept. The window is remarkable in anti-freezing capability, is high in transparency in a cold state, is high in response speed after being heated, is quickly turned into an opaque state, and can effectively modulate the sunlight transmittance.
