Abstract
Disclosed is a thermochromic intelligent window with an adjustable emissivity. The thermochromic intelligent window includes a window frame. A glass assembly is assembled in the window frame and includes a glass substrate. One side of the glass substrate is deposited with a metal oxide coating for adjusting the glass substrate, the metal oxide coating has a low-emission function, and the metal oxide coating is a layer of transparent indium tin oxide film. A solar-adjusted high-emission portion is assembled on the other side of the glass substrate and includes a first polyethylene layer. A hydroxypropyl cellulose hydrogel layer is assembled on an upper portion of the first polyethylene layer. A second polyethylene layer is further assembled on the hydroxypropyl cellulose hydrogel layer. The hydroxypropyl cellulose hydrogel layer is wrapped between the first polyethylene layer and the second polyethylene layer.
